3. Installation Guide

This product features a plug-and-play design for easy installation. No computer reprogramming is typically needed.

3.1 Tools Required

• Gloves (optional, for handling)

3.2 Installation Steps (T10 Connection Method)

Refer to the diagram below for visual guidance. The process is similar for other connector types.

Figure 2: T10 Connection Method Diagram.

1. Preparation: Ensure your vehicle's engine is off and the parking brake is engaged. If possible, disconnect the negative terminal of your car battery for safety.
2. Locate Original Lights: Identify the existing license plate light housings on your vehicle.
3. Remove Original Housing: Carefully use a flathead screwdriver or pry tool to unclip and remove the original license plate light housing from its mounting position.
4. Disconnect Wiring: Disconnect the electrical connector from the original light housing.
5. Remove Halogen Bulb (if applicable): If your original housing uses a separate halogen bulb, gently twist or pull it out.
6. Connect New LED Light:
   • For T10 connections: Insert the connector from the new LED light into the OE socket where the halogen bulb was removed.
   • For other direct connectors: Plug the vehicle's wiring harness directly into the new LED license plate light.
7. Test Functionality: Before fully reassembling, temporarily reconnect the battery (if disconnected) and turn on your vehicle's lights to ensure the new LED lights illuminate correctly. If they do not light up, check the connection and ensure proper polarity (some LEDs are polarity sensitive; try flipping the connector if it doesn't work initially).
8. Secure New Light: Carefully push the new LED license plate light assembly back into its mounting slot until it clicks securely into place. Ensure a snug fit to prevent water ingress.
9. Repeat: Repeat the process for the other license plate light.

4. Operating Instructions

Once installed, the LED License Plate Lights operate automatically with your vehicle's exterior lighting system. They will illuminate when your headlights or parking lights are turned on.

5. Maintenance

These LED license plate lights are designed for long-lasting, maintenance-free operation. However, occasional inspection and cleaning can help maintain their appearance and performance.

• Cleaning: If the lens becomes dirty, gently wipe it with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the plastic.
• Inspection: Periodically check the lights for any signs of damage, loose connections, or moisture ingress. While the product is waterproof, extreme conditions or improper installation can sometimes lead to issues.
• No Bulb Replacement: As these are LED units, individual bulbs cannot be replaced. If a unit fails, the entire assembly typically needs to be replaced.

8. User Tips

• Brightness Adjustment: If you find the LED lights too bright, a user tip suggests applying a 5% window tint film over the lens to achieve a preferred brightness level.
• Compatibility Confirmation: Users have confirmed these lights work perfectly with no error messages on vehicles such as Golf 7 (2014, 2016), Polo 5, and Passat CC (2011).
• PWM Control Warning: Be aware that if your car uses Pulse Width Modulation (PWM) for brightness control of the license plate lights, these LEDs might produce a buzzing sound when brightness is adjusted. This indicates potential incompatibility with such systems.
