How To Install Fox Body Mustang Headlights | 1987-1993 Mustang

Replacing the headlights on your 1987–1993 Fox Body Mustang is one of the simplest and most rewarding upgrades you can make. Over time, the factory lights can become faded, yellowed, or cracked, hurting both your car’s appearance and visibility at night. Whether you're restoring your Mustang to its original look or going for a custom style with smoked or ultra-clear lenses, installing new headlights can dramatically freshen up the front end.

In this step-by-step guide, we’ll walk you through how to remove your old lights and install a new set with basic tools right in your garage. No guesswork—just a clean, easy upgrade that brings your Fox Body back to life.

We removed the front bumper for this install, but it is not necessary for installation. If replacing headlights in the car, it is recommended to remove the air intake system and battery for more working room.

Installation Instructions:

1. Disconnect the bulb sockets and use a 7/16" wrench to remove the retaining nuts from the back of the lights.
   
   
   
   
2. Remove the headlights from the vehicle. Remove the park light first, then side marker, and then the headlight assembly.
   
   
   
   
3. If your backing plates are still good, transfer them over to the new headlights. If you are installing new backing plates, install them at this time.
   
   
   
   
4. Reverse the removal steps to install the headlights and tighten your hardware.
   
   
   
   
5. Transfer over your headlight bulbs to the new headlights.
   
   
   
   
6. Reconnect your headlight bulb sockets.
   
   
   
   
7. Test for operation and you are done!
