* Partial small probability issues, just special circumstances *

✈️ 1. Shipping & Tracking
1.1. How long does it take to ship my order?+
Orders are typically processed within 1-3 business days. Estimated delivery after dispatch:
• Europe / North America / Asia / Oceania: 3-15 days
• Rest of World: 3-20 days.
1.2. Where can I track my package?+
Once shipped, you will receive an email titled "A shipment from order #12345 is on the way". Click the tracking number in that email to open the live tracking page or use tracking page: zenebricks.com/pages/order-tracking. If you have any issues, please contact us.
1.3. My tracking status hasn't updated in 5+ days.+
While rare, delays can occur due to weather, customs clearance, or carrier backlogs. Please email us your order number — we will push the logistics carrier for an update ASAP. Please don't worry; we will get this sorted out for you.
1.4. Tracking says "Returned to Sender". Why?+
The package was returned to the local warehouse after two failed delivery attempts. This typically happens if the address or zip code was incorrect, or if the driver could not reach you.

Please send your full, correct shipping address (Name, Phone, Email, Address, City, State, Country) to [email protected] and we will arrange a new shipment for you. Verifying address accuracy is the best way to speed up re-delivery.
1.5. It says "Delivered" but I haven't received it.+

Carriers sometimes mark items as delivered slightly early, or leave packages in unexpected locations. Follow these steps to locate your package or escalate quickly.

📦

DELIVERED BUT NOT RECEIVED — ACTION GUIDE

1

Verify the delivery address on your order

Open your order confirmation email and confirm the shipping address shown matches your actual address. A single wrong digit in a zip code can send a package to a different location.

Address is correct

Proceed to Step 2.

Address contains an error

→ Fault B. Take a photo of your actual door/entrance showing the address number, then proceed to Step 3.

▼
2

Check all nearby delivery locations

Carriers often leave packages in less-obvious safe spots. Check every location below before assuming the package is lost.

  • Mailbox, letterbox, or parcel locker
  • Front porch, back door, or side gate
  • With a neighbour (check 2–3 nearby doors)
  • Building reception desk or property management office
  • Inside a garage or behind a bin
Package found!

Problem resolved. Enjoy your kit!

Not found — but fewer than 48 hours since "delivered"

Wait 48 hours. Carriers sometimes scan items as delivered up to 24 hours early. Check again the next day.

🧱 2. Product & Compatibility
2.1. Is the LEGO set included?+
No. We sell LED Lighting Kits and motor modification kits only. The LEGO set shown in product images is for demonstration purposes and is not included.
2.2. Are your parts compatible with LEGO?+
Yes. Our parts are 100% compatible with LEGO® and other major brick brands (MOC, BrickLink). They are designed to fit seamlessly with standard brick sets without damaging original LEGO pieces.
2.3. What is the difference between Classic, Remote, and Sound versions of Light Kits?+
• Classic Version: On/off via physical switch or USB — fixed brightness, no wireless control.
• Remote Version: Wireless control of brightness, light zones, and modes (steady, breathing, flashing).
• Sound Version: Plays music; import MP3 files via Micro USB connection to a computer.
• IR Version: Infrared sensing — e.g., wave your hand to activate the lights.
2.4. Can I buy individual parts (e.g., extra wires, battery boxes)?+
Yes. Visit our DIY Accessories section, or email [email protected] with the specific part you need for a custom quote.
2.5. What is the difference between Basic and Advanced motor kits?+
Advanced versions have more features, use more motors, and require more modification steps. Detailed specifications for each product are listed in the product description on the product page.
2.6. Does the motor kit preserve the original LEGO gearbox?+
In most cases yes. However, some small cars don't have enough space for the motor alongside the gearbox. When the gearbox is retained, set it to neutral when using the remote control — speed is controlled by the remote and is not affected by the gear setting.
2.7. How long do the LED lights last? What is the warranty?+
Our LED lights have a rated lifespan of up to 50,000 hours. All products come with a 1-year limited warranty against manufacturing defects. Contact us for free replacement or repair within the warranty period (excludes damage from improper use or accidental breakage).
2.8. Can I install both the LED light kit and the motor kit on the same LEGO model?+
Yes. The two kits are fully compatible and use independent power supplies. We recommend installing the motor kit first, then the LED light kit. They will not interfere with each other's functionality.
📖 3. Installation & Manuals
3.1. Where is the manual? I only see a small card.+

We use eco-friendly digital PDF manuals instead of printed booklets to reduce paper waste. There are three ways to access your manual — try them in order.

📖

HOW TO FIND YOUR INSTRUCTION MANUAL

1

Scan the QR code on the card inside your package

The small card in your package has a QR code that links directly to your PDF manual. Point your phone camera at it — a link should appear automatically (no extra app needed on most phones).

Tip for iPhone users: Open the standard Camera app and point it at the QR code — a banner will appear at the top of the screen with the link. No need to download a QR scanner app.

Manual opened successfully

You can bookmark or download the PDF for offline use.

Email Us for Manual
3.3. Should I build the LEGO set first?+
For LED light kits: Yes. Build the LEGO set fully using the official LEGO instructions before installing any lights.

For Power Functions motor kits: Most kits require modification during the assembly process. However, some versions (42207, 42206, 42177, 42171) offer a post-assembly installation method. Please check the specific product page for details.
3.4. The wires seem too short.+

In the vast majority of cases, wires that "seem too short" are actually long enough — the issue is routing. Work through these checks before requesting an extension.

🔌

WIRE TOO SHORT — DIAGNOSIS GUIDE

1

Follow the routing path in the instructions exactly

Each wire is cut to match the precise routing path shown in the manual. Detours — wrapping around the outside of bricks, routing over the top of structures, or any path that differs from the instructions — consume extra length and make wires appear too short.

Key routing rules: Always thread wires through inside channels and gaps between bricks. Never route wires across the surface or around the outside of a structure.

Routing corrected — wire now reaches

Problem resolved. Continue with installation.

Routing is correct per instructions, but wire is still short

Proceed to Step 2.

▼
2

Confirm you are using the correct wire for this position

Each kit contains wires of several different lengths designed for specific zones of the model. Using a short-zone wire for a long-zone position will always result in it being too short. Check the bag number on the wire against the instruction manual's parts diagram.

Wrong wire identified — swapped to correct one

Problem resolved. The wire you were using belongs to a different installation position.

Correct wire confirmed, but it is genuinely too short

→ Fault A. The wire may have been produced in the wrong length. Proceed to Step 3.

▼
3

Contact us — we'll send a free extension wire

Email [email protected] with the following so we can ship the correct extension immediately:

  • Your order number
  • Bag number the wire came from (printed on the small bag label)
  • Instruction manual step number where the wire is too short
  • Optionally: a short photo or video showing the gap

FAULT REFERENCE

Fault AWire produced in incorrect length — Routing is confirmed correct and the correct wire is being used, but it does not reach the destination. Free extension wire will be sent.

Providing the bag number and instruction step speeds up our response significantly — no back-and-forth needed.

Request Free Extension Wire
3.5. I accidentally pinched or broke a wire.+
The wires are thin to fit between LEGO bricks and can be damaged by sharp bends (greater than 90°) or excessive force. Do not attempt to repair a broken wire yourself — this can cause short circuits. Contact us with the bag number, a photo of the damage, and your order number. We frequently provide free replacement wires, subject to our warranty policy.
3.6. How do I hide the light wires to keep the model neat?+
1. Thread wires through the hollow structures, gaps, and internal cavities of the model — most LEGO sets have built-in channels for this.
2. Use the included cable clips to secure wires to the back or bottom of the model.
3. Never fold wires at angles greater than 90° or force them around sharp corners.
4. For excess length, loosely coil (never fold tightly) and tuck inside an internal cavity.
3.7. Do I need any special tools to install the kit?+
No special tools are required. All necessary accessories (cable clips, adhesive tape, connecting pieces) are included. Installation requires only your hands and the step-by-step instructions provided.
3.8. Instructions for Light Kit Remote Control?+
Considering that our lighting kits come in various styles to match different LEGO set designs, we mainly offer four types of remote controls. You can compare your remote control with the following list to check the corresponding remote control functions.
ZENE Bricks manual 18 keys remote control for light kit ZENE Bricks manual RGB remote control for light kit ZENE Bricks manual functional remote control for light kit ZENE Bricks manual 15 keys remote control for light kit
💡 4. Technical Support
4.1. My lights won't turn on at all.+

Most issues come from a single faulty component. Follow each step in order — stop as soon as you find your fault.

LED FAULT ISOLATION GUIDE

1

Test each power source independently with one LED

Do not use the expansion board yet. Take a single LED and connect it directly — first to the Battery Box, then (separately) to the USB cable. Record the result for each.

TEST A — Battery Box
Connect LED directly to Battery Box.
Lights up → Battery Box is working.
No light → Battery Box is suspect.
TEST B — USB Cable
Connect LED directly to USB cable.
Lights up → USB supply is working.
No light → USB cable/adapter is suspect.
Both Test A and B light up the LED

Both power sources confirmed working. This LED is your "verified LED". Continue to Step 2.

Only one source lights up

The failing source is faulty → Fault A. Use the working source as your verified power and continue to Step 2.

Neither source lights up

Try 2–3 different LEDs. If still dark → both power sources failed → Fault A. If a different LED works, the first LED was faulty — use the working LED as your verified LED and continue to Step 2.

▼
2

Connect verified LED to Port A of the expansion board

Plug your verified LED into Port A using a confirmed working power source. Watch what happens the moment you connect it.

LED lights up normally

Port A and the board confirmed working. Continue to Step 3.

LED does not light up — system stays on

Port A may be faulty. Try Port B and every other port.
— Works elsewhere → Fault B.
— Fails on all ports → Fault D.

System shuts off instantly when plugged in

Short circuit detected. Remove this LED immediately → Fault C.

▼
3

Add remaining LEDs one by one

Port A is working. Plug in remaining LEDs one at a time, confirming the system stays on before adding the next.

All LEDs added with no issue?
All components healthy. System fully operational.
One LED shuts system down?
That LED has a short circuit → Fault C. Remove it; rest work normally.

FAULT REFERENCE

Fault ABattery Box or USB cable/adapter faulty — One or both power sources fail to light a verified LED when connected directly.
Fault BSpecific port faulty — Verified LED works on other ports but fails on one specific port.
Fault CShort circuit — LED wire or connector — A specific LED causes the entire system to shut off the instant it is plugged in.
Fault DExpansion board defective — Verified LED works on direct power but fails on every port of the expansion board.

Describe your test results when contacting us (e.g. "Step 1 — Battery Box failed, USB worked" or "Step 2 — system shut off on Port A").

Submit Diagnostic Result
4.2. Some lights work, but others don't.+

This usually means the main power is working, but one light, connection, or expansion board port is not. Follow these checks in order.

💡

PARTIAL LIGHT FAILURE DIAGNOSTIC GUIDE

1

Test the non-working light in a known working port

Move one non-working light to a port that is already powering another light correctly.

The light works in the new port

The original port is likely faulty → Fault A.

The light still does not work

Issue is with the light or its connection. Continue to Step 2.

▼
2

Check the cable and connector

Inspect for loose connections, incomplete insertion, visible damage, or broken wires. Re-seat the connector firmly before testing again.

Connection issue found and corrected

Test again. If it now works, issue resolved.

No cable/connector issue found

Continue to Step 3.

▼
3

Verify polarity and installation method

Check that the light is connected with the correct positive/negative orientation and installed exactly as shown in the instructions.

Polarity/installation corrected — now working

→ Fault C (resolved).

Everything correct, light still does not work

Light is likely defective → Fault B. Contact support with photos and bag reference.

FAULT REFERENCE

Fault APort failure — Light works in another port but not the original one.
Fault BLight defective — Same light fails even in a working port, no wiring issue identified.
Fault CInstallation issue — Loose connection, reversed polarity, or incorrect installation — resolved after correction.

Include: which light failed, whether it worked in another port, and any checks already completed.

Submit Diagnostic Result
4.3. The lights are dim or flickering.+

Dim or flickering lights are almost always caused by insufficient or unstable power. Follow these steps to identify and fix the root cause.

🔆

DIM / FLICKERING LIGHTS DIAGNOSTIC GUIDE

1

Replace batteries or verify USB adapter rating

Low or unstable power is the #1 cause of dim and flickering LEDs.

BATTERY BOX
Install brand-new alkaline AA/AAA batteries. Avoid rechargeables — their 1.2 V is lower than alkaline 1.5 V and causes dimming.
USB POWER
Use a 5 V / 1 A (or higher) adapter. Low-power chargers (500 mA) are insufficient for larger sets.
Lights now bright and steady

→ Fault A resolved (depleted power source).

Still dim/flickering with fresh power

Continue to Step 2.

▼
2

Check connections and inspect for short circuits

Loose connectors or a partially shorted wire force the power supply into protection mode, reducing voltage. With power on, gently touch each wire and the expansion board — any noticeably warm component is causing the issue.

Warm/loose component found and removed

Lights return to normal → Fault B. Contact us to replace that component.

No warm or loose components found

Continue to Step 3.

▼
3

Reduce the number of LEDs on one power source

Disconnect roughly half the LEDs and observe whether the remaining lights become brighter.

Remaining lights are brighter

→ Fault C (overload). Use a second power source, or upgrade to a 5 V / 2 A USB adapter.

Still dim even with fewer LEDs

Contact support and describe all three steps already completed.

FAULT REFERENCE

Fault ADepleted/insufficient power — Batteries were weak or USB adapter current was too low.
Fault BShort circuit in wiring or component — Warm component caused protection mode to reduce output voltage.
Fault CPower overload — Combined current draw of all LEDs exceeded the capacity of the single power source.

Describe all steps completed and each result (e.g. "Step 2 — found warm wire on Bag 3 LED" or "Step 3 — still dim with only 5 LEDs").

Submit Diagnostic Result
4.4. Can I connect multiple kits to one power source?+
Each kit uses its own independent power supply. You can install multiple kits, but if lights appear dim or flash abnormally it means the combined load is too high for one power source. In that case, use a separate power source for each kit or upgrade to a 5 V / 2 A USB adapter.
4.5. Is it safe to leave the lights on 24/7?+
Not recommended. Although our LEDs are energy-efficient, we advise turning the lights off when the model is not being viewed, to prevent premature wear on the power supply and extend the overall lifespan of the kit.
4.6. My kit is missing many parts, lights, or bags.+

Most "missing parts" reports are caused by using the wrong instruction version. Verify your manual first before contacting support.

📦

PARTS VERIFICATION GUIDE

1

Identify your product version

CLASSIC (CV)
No remote control. Look for CV on instruction cover.
REMOTE (RCV)
Includes remote control. Look for RCV on instruction cover.

⚠ Version 2 (V2): If your product title includes "Version 2" or "V2", you must use the V2 instruction manual. V1 and V2 have different parts lists.

▼
2

Verify you are using the correct instruction manual

Locate the version code on the instruction manual cover. It must match what you identified in Step 1.

Manual matches — parts now match the list

Problem resolved. You were using the wrong version. Proceed with assembly using the correct manual.

Manual does not match product version

→ Issue B. We provided the wrong manual. Continue to Step 3.

Manual matches, but parts still don't match

→ Issue A (genuine shortage). Continue to Step 3.

▼
3

Contact support with photos

  1. Clear photo of all parts received laid out on a flat surface
  2. Photo of the instruction manual cover showing the version code
  3. Your order number
  4. Brief description of which parts appear to be missing

Issue BWrong manual provided by us — Product version does not match the supplied instruction manual version code.
Issue CUser downloaded wrong manual — Incorrect version downloaded from website or third-party source.
Contact Support with Photos
4.7. The Remote Control isn't working.+

Most remote control issues are resolved by following these diagnostic steps in order. Stop as soon as your remote starts working.

📡

REMOTE CONTROL DIAGNOSTIC GUIDE

1

Remove the battery insulating tab

Check the battery compartment for a clear plastic tab between the battery and contacts. This tab prevents drain during shipping and must be removed before first use.

Tab found and removed — remote now works

Done!

Tab removed but remote still not working / no tab present

Continue to Step 2.

▼
2

Verify battery polarity and replace with a fresh battery

Confirm the battery is oriented correctly (+ and − match the compartment markings). Then install a brand-new CR2032 (or CR2025) battery — batteries can be drained from storage even if unused.

Remote works with new battery

Old battery was depleted. Problem resolved.

Still not working

Continue to Step 3.

▼
3

Check the indicator LED blink pattern

Press any button and observe the LED indicator on the remote.

Single blink per press — remote is transmitting

Remote is OK. Issue is with receiver or pairing. Continue to Step 4.

Rapid multiple flashes

Low battery warning. Replace battery and retry (return to Step 2).

LED does not blink at all

Remote is defective → Fault A. Contact support.

▼
4

Code matching (white remote only)

If you have the white remote, it requires code pairing with the receiver chip:

  1. Turn off power to receiver chip.
  2. Wait 3 seconds.
  3. Turn on power to receiver chip.
  4. Immediately press and hold the red button for 2 seconds.
  5. Chip indicator lights light up one by one = pairing successful.
Chip lights lit one by one — pairing successful

Remote now controls the lights normally.

No response from chip — pairing failed

Retry the procedure. If it fails again → Fault B.

Using black remote

Black remotes need no pairing. If LED blinks but lights don't respond → Fault C.

FAULT REFERENCE

Fault ARemote defective — Indicator LED does not blink with fresh battery correctly installed.
Fault BCode matching failure (white remote) — Remote LED blinks but chip lights do not respond after multiple pairing attempts.
Fault CReceiver chip defective — Remote LED blinks normally but lights do not respond to any commands.

Describe your test result (e.g. "Step 3 — LED does not blink" or "Step 4 — white remote pairing failed twice").

Submit Diagnostic Result
4.8. The remote blinks, but lights don't respond.+

If the remote's LED blinks, the remote itself is working. The issue is in the signal path between remote and receiver. Follow these steps in order.

📶

REMOTE SIGNAL DIAGNOSTIC GUIDE

1

Distinguish normal blink from low-battery blink

NORMAL BLINK
1 flash per press → Remote is transmitting normally.
LOW-BATTERY BLINK
Rapid flashes per press → Replace CR2032 battery first.
Single blink confirmed — battery good

Continue to Step 2 to check the receiver.

Rapid blink — replaced battery, now single blink

→ Fault A resolved. Test if lights respond. If still no response, continue to Step 2.

▼
2

Check receiver board connections and clear obstructions

  • Connections: Confirm all LEDs/motors are plugged firmly into the receiver board ports.
  • Obstruction: Remove any LEGO bricks blocking the receiver's sensor eye/antenna.
  • Distance: Test at close range (within 1 metre) to rule out range issues.
Issue found and corrected — lights respond

→ Fault B resolved.

Connections clear, still no response

Continue to Step 3.

▼
3

Reset receiver board & re-pair code (white remote only)

Unplug power, wait 10 seconds, reconnect. Then for white remotes: hold the red button for 2+ seconds immediately after power-on until chip lights sequence.

Lights now respond after reset / pairing

Problem resolved.

Still no response

Receiver chip is likely defective → Fault C. Contact support with a short video.

FAULT REFERENCE

Fault ARemote battery depleted — Rapid blinking = critically low. Resolved by replacing CR2032.
Fault BReceiver connection or obstruction — LEDs/motors not properly seated, or receiver sensor was blocked.
Fault CReceiver chip defective — All connections correct, pairing attempted, but chip does not respond.
Submit Diagnostic Result
4.9. What battery does the remote use?+
Most of our remote controls use a CR2032 3 V button cell battery. The specific model is printed on the back of the remote and in the installation manual. Available at most supermarkets, electronics stores, or online retailers.
4.10. LEDs are dim, but the battery box indicator light is bright.+

A bright battery box indicator combined with dim LEDs means the battery box has entered short-circuit protection mode — a safety feature that reduces output voltage when it detects an abnormal load. Follow these steps to find the cause.

🔋

BATTERY BOX PROTECTION MODE DIAGNOSTIC

1

Unplug all components and reset the battery box

  1. Unplug all LEDs and motors.
  2. Turn off the battery box switch.
  3. Wait 5 minutes for the protection circuit to reset.
  4. Turn on — indicator should be bright.
Battery box reset — indicator bright

Protection mode cleared. Continue to Step 2 to find the cause.

Indicator still dim with nothing connected

Battery box itself is defective → Fault B.

▼
2

Reconnect LEDs and motors one at a time

With battery box on, add components one at a time. After each addition, confirm the LEDs stay bright before adding the next.

All components reconnected — lights bright throughout

→ Fault C (was a transient event). System now working normally. Monitor for recurrence.

LEDs go dim when one specific component is plugged in

That component is triggering protection mode. Remove it and note the bag number. Continue to Step 3.

▼
3

Verify the suspect component in isolation

Reset battery box again, then connect only the suspect component. This confirms it's the cause and not a load coincidence.

Bright alone — only dims with many connected

→ Fault C (overload). Use a second power source or upgrade to a 5 V / 2 A adapter.

Dim even when connected alone

→ Fault A. This component has an internal short. Do not use it — contact support for free replacement.

4.11. How long does the rechargeable battery box last on a single charge?+
Battery life depends on the number of lights/motors connected and brightness setting:
• LED kit (10–15 LEDs): 4–6 hours at full brightness. Large sets with many LEDs drain faster.
• Motor kits: 1–3 hours depending on load and usage frequency.
Charge for 4–6 hours for a full charge. The indicator turns from red to green when fully charged.

MISSING PARTS — RESOLUTION GUIDE

1

Identify the missing part using the manual's parts list

Open your instruction manual to the parts list page (usually the first 1–2 pages). Match each item in the list against what you received. Physically lay out all received parts on a flat surface to make it easier to spot what is missing.

⚠ Check your manual version first! If you are using a different version manual from what was shipped, the parts lists will differ and parts will appear "missing" when they are actually included. See FAQ #33 for version verification.

Photograph all received parts and the parts list

Take two clear photos before contacting us — these allow us to verify and process the replacement without needing extra back-and-forth messages.

PHOTO 1
All received parts and bags laid out on a flat surface. Ensure everything is visible and well-lit.

Email us — free replacement dispatched within 24 hours

Email [email protected] with both photos and the following details. You do not need to return the rest of the package.

  • Your order number

  • Both photos from Step 2

✅ What happens next: We verify your parts inventory from the photos, identify the missing component, and dispatch it to you free of charge — usually within 24 hours of receiving your email.

Having both photos ready before emailing us is the single biggest factor in speeding up your replacement. We can process photo-based requests immediately without additional questions.

DEFECTIVE PRODUCT — RESOLUTION GUIDE

Document the defect with photos or a short video

Good documentation is the most important factor in getting a fast resolution. The clearer your evidence, the faster we can approve a replacement or refund — often without any back-and-forth.

  • Photo or video of the defect (e.g., cracked housing, visibly broken wire, LED that won't illuminate)
  • If it's a functional issue (e.g., lights flicker), a short video (5–15 seconds) is ideal
  • Photo of the whole kit showing which component is affected

Email us with your documentation

  • Your order number
  • A clear description of the defect (what happens, when it happens)
