4. Setup and Installation
Follow these general steps for installing the LED interior lights. Specific removal procedures for your vehicle's light covers may vary; consult your vehicle's service manual if needed.
- Prepare the Vehicle: Ensure the vehicle's ignition is off and the power is disconnected to prevent electrical shorts or injury.
- Locate Existing Bulbs: Identify the interior light fixtures where you intend to replace bulbs (e.g., front dome, rear map, trunk, glove box).
- Remove Light Covers: Carefully pry open or unclip the plastic covers of the light fixtures. Use a plastic trim removal tool to avoid scratching surfaces.
- Remove Old Bulbs: Gently pull out the existing incandescent bulbs. They may be hot if recently used.
- Install LED Bulbs: Insert the new LED bulbs into the sockets. Ensure a snug fit.
- Test Functionality: Before reattaching covers, briefly restore power to the vehicle and test each newly installed LED bulb. If an LED bulb does not illuminate, remove it, flip it 180 degrees, and reinsert it to correct the polarity.
- Reattach Covers: Once all bulbs are working correctly, carefully snap or clip the light covers back into place.
