Installation / Application:
Difficulty: 2/5

Suggested Tools:
Phillips screwdriver or appropriate driver for lens screws
Flathead screwdriver or trim tool (if applicable)
Clean cloth
Gloves
Silicone grease or rubber conditioner (optional for gasket)
Instructions:
Park the vehicle on a level surface, turn off the ignition, and disconnect the battery to avoid electrical contact while working on the lights.
Open the trunk or access panel to reach the tail light housing from the inside of the quarter panel.
Remove the retaining screws or fasteners that secure the existing tail light lens using the appropriate screwdriver; set screws aside for reuse if undamaged.
Carefully pull the old lens away from the housing. If the lens is brittle or stuck, use a trim tool or flathead screwdriver gently to pry it free without damaging the housing.
Inspect the housing, bulb socket, and gasket for corrosion, cracked plastic, or damaged seals; replace any worn gaskets or bulbs as needed.
Clean the mounting surface and gasket channel with a clean cloth. Apply a small amount of silicone grease or rubber conditioner to a replacement gasket if available.
Position the new red lens (fits LH or RH) over the housing, align mounting holes, and install the original or supplied screws. Hand-start screws to avoid cross-threading, then tighten evenly until snug — do not overtighten to prevent cracking the lens.
Reconnect the battery and test the tail light functions (running light, brake light, and turn signal) to confirm proper operation.
Reinstall any interior panels or trim removed for access. Dispose of the old lens in accordance with local regulations.
