Difficulty: Beginner · About 20 min · Ford Mustang

Replace the headlight assembly on a 1999-2004 Ford Mustang.

Steps

1. Handle the new bulbs carefully

   Avoid touching the bulb's glass with your fingers, since skin oil can burn into it and foul the light; clean it with rubbing alcohol and a soft cloth if that happens.

2. Remove the old headlight assembly

   Pull the tabs anchoring it, lay a cloth on the bumper to protect the paint, pull the assembly out, then unplug the harness and bulbs.

3. Install the new headlight assembly

   Plug in the bulbs and harness, set the assembly into its mounting using a rag to protect the paint, then anchor it with the two tabs.

Check your vehicle’s repair manual for exact specifications and fit.
