The headlight bulbs of your Ford Expedition will burn out in time like any bulb. Because lights are an important safety feature, replace a burnt headlight immediately. Be careful not to get any natural oils from your hands on the bulb glass, or it will be damaged.
Open the hood and disconnect the negative cable from the truck battery. Leave the hood open so you can access the headlight from the back.
Push the clamp housing clamp clips backward; These clips are near the top of the headlight and the front frame of the truck. Pull the clips up after pushing to release the headlight housing.
Pull the headlight housing out and away from the truck so that you can access the bulb retaining ring from the back of the lamp.
Turn the bulb retaining ring counterclockwise from the back and remove the bulb and the retaining ring from the headlight housing. Pull the bulb out to remove it from the socket assembly.
Insert the new h3 headlight bulb led into the mounting socket, making sure not to touch the bulb glass with bare fingers. Insert the socket with the bulb into the headlight housing and tighten the retaining ring.
Place the headlight housing in place on the truck and install the retaining housing clips.
Reconnect the battery cable and close the hood.
Tips and warnings
- Wear rubber gloves when installing the new headlight bulb so as not to touch the glass with bare skin.
