This article applies to the Ford Mustang V6 and Mustang GT (1994-2004).

The Ford Mustang and the Mustang GT are attractive, loud cars, but that's not enough to rely on at night. In order to get to the tail light bulb, you have to remove the tail light assembly. So whether you want to replace the bulb, or if you want to replace the assembly, the process is the same. Read on to learn how you can do this procedure on your own.

Materials Needed

  • Flat head screwdriver
  • 11mm wrench
  • New bulb or assembly

Step 1 – Disconnect your battery

Even though this is not completely necessary, safety should always come first. Open your hood and remove the negative (black) battery cable.

Step 2 – Remove trunk liner

Open the trunk of your mustang, and remove the retainers holding the liner near the tail light you will be replacing. Use your flat head screwdriver and turn it counterclockwise until it comes off. Then fold the liner and the panel inside of it away from the tail light.

Step 3 – Remove tail light assembly

Disconnect the connector on the inside by the assembly. Then use your 11mm wrench to remove the four bolts holding the tail light assembly in place. When removed, pull the tail light assembly out gently.

Step 4 – Replace the bulb

To remove the bulb, turn it counterclockwise and replace with a new one. If you want to install a new assembly, simply connect all the bulbs to the new assembly the same way it was connected to the old one by turning it clockwise and locking it into place.
