Pre-Installation Preparation

1. Park the vehicle on a flat, level surface and turn it off.
2. Ensure the trunk is fully open.
3. Turn off all vehicle lights to prevent short circuits.
4. Clean the mounting area above the license plate to remove dust and debris.
5. Inspect the new assembly for any damage before installation.

Step-by-Step Installation

1. Remove the Old Assembly: Locate the light above the license plate. If secured by clips, use a plastic pry tool to gently pry it out. If secured by a screw, remove the screw first. Once loose, press the connector clip to disconnect the wiring harness.
2. Install the New Assembly: Align the new assembly's electrical connector with the vehicle's harness and push until it clicks. Align the assembly with the mounting slot and press firmly until it clicks into place (or reinstall the mounting screw if applicable).

Post-Installation Test

Close the trunk and turn on the vehicle's parking lights or headlights. Verify that the new light illuminates uniformly without flickering or dark spots. Open the trunk again to ensure the assembly is securely mounted with no gaps.

Important Precautions

• Always turn off vehicle lights before starting to avoid electrical shorts.
• Use only a plastic pry tool to prevent scratching the vehicle body.
• Ensure the electrical connector is fully seated to avoid error messages or flickering.
• Do not touch the LED light source or inner lens surface with bare hands.
• Do not use high-pressure water to rinse the assembly within 24 hours of installation.

Maintenance

Regularly clean the lens with a soft, damp cloth. Avoid abrasive cleaners, gasoline, or harsh chemicals. Periodically inspect the assembly for signs of damage or water ingress.
