Installation Guide

1. Locate the Light Housing: Identify the plastic lens cover of the light you wish to upgrade (e.g., dome light).

2. Remove the Cover: Gently pry off the clear plastic lens cover using a trim tool or your fingers.

3. Remove the Old Bulb: Carefully extract the existing halogen festoon bulb by sliding it out of its metal contact clips.

4. Insert the New LED: Align the metal contacts on each end of the new LED bulb with the clips in the socket and press it firmly into place.

5. Test Before Reassembly: Turn on the vehicle's ignition (or open the door) to test the new bulb lights up correctly.

6. Replace the Cover: Snap the lens cover back into position.

Tip: The bulb is not polarity-sensitive, meaning it will work regardless of which direction it is inserted into the festoon clips.

Frequently Asked Questions (FAQ)

Q1: Will this bulb fit my car?
