5. Installation
These LED festoon bulbs are designed for easy, direct replacement of your vehicle's existing halogen bulbs. Ensure you have selected the correct size (31mm, 36mm, 39mm, or 41mm) to match your vehicle's bulb housing.
General Installation Steps:
- Safety First: Turn off your vehicle's ignition and disconnect the battery to prevent electrical hazards.
- Locate the Bulb: Identify the light fixture where you intend to replace the bulb (e.g., dome light, map light, trunk light, license plate light).
- Remove the Cover: Carefully pry open the plastic cover of the light fixture using a plastic trim removal tool to avoid scratching.
- Remove Old Bulb: Gently pull out the old halogen festoon bulb from its metal clips. Be cautious as the old bulb might be hot if recently used.
- Insert New LED Bulb: Insert the new AHLTD LED festoon bulb into the metal clips. Ensure it is securely seated.
- Test Functionality: Reconnect the vehicle's battery and turn on the corresponding light to test the new LED bulb. If the bulb does not light up, remove it, flip it 180 degrees (LEDs are polarity sensitive), and reinsert it. Test again.
- Replace Cover: Once confirmed working, snap the light fixture cover back into place.
