5.2 Installation Steps
- Prepare the Vehicle: Park the vehicle on a level surface, engage the parking brake, and turn off the engine. Open the trunk or tailgate to access the tail light area.
- Disconnect Battery (Optional but Recommended): For safety, disconnect the negative terminal of the vehicle's battery.
- Access Mounting Bolts: Locate the mounting bolts or nuts that secure the existing tail light assembly. These are typically accessible from inside the trunk or behind a trim panel. Remove any trim panels if necessary.
- Remove Old Tail Light: Carefully remove the mounting bolts/nuts. Gently pull the old tail light assembly away from the vehicle. It may be held in place by alignment pins or clips.

- Mount New Tail Light: Carefully align the new tail light assembly with the vehicle's body and push it into place. Ensure the alignment pins (if present) engage correctly.
- Secure Mounting Bolts: Reinstall and tighten the mounting bolts/nuts. Do not overtighten, as this can crack the plastic housing.
- Reconnect Battery: Reconnect the negative terminal of the vehicle's battery.
- Test Functionality: Turn on the vehicle's ignition and test all tail light functions: running lights, brake lights, turn signals, and reverse lights. Ensure all lights illuminate correctly and without flickering.
