How to Install Head Lights on a 2002 Mercury Mountaineer

Head light bulbs are a normal maintenance item. Don't be surprised if you have to replace your head lights after a couple of yours of driving. The 2002 Mercury Mountaineer has a fairly simple head light setup. Since the Mercury Mountaineer and the Ford Explorer are clone vehicles, these instructions will also apply to the Ford Explorer.

Things You'll Need

• Replacement bulb 9007 (high-beam or low-beam)

Instructions

1. Turn your head light switch and engine off, then pop the hood.

2. Inspect the rear of the headlamp assembly. Locate the two retainer pins behind each headlamp assembly. Remove the pins with your hand.

3. Push the headlamp assembly forward to create enough work room to change the head lights.

4. Twist the protective housing counterclockwise to remove it from the headlamp assembly. Pull the electrical module to disconnect it.

5. Twist the bulb retainer ring counterclockwise to remove it from the headlamp assembly. Pull the old bulb off and discard.

6. Place the new bulb in the retainer ring, then reconnect the electrical module and replace the protective cover.

7. Push the headlamp assembly back in place and replace the retainer pins to secure it.

Tips & Warnings

• Do not touch the glass part of the bulb. If you accidentally touch it, wipe it clean. Oil from your hands can damage the bulb when it is turned on.
