Replace the damaged or missing third brake light lens on your 1986-1993 Mustang LX coupe with this OE-style replacement from 5.0 Resto! Located at the bottom of the rear window on the rear package tray, this brake light illuminates with the tail lights to increase rear safety and visibility. Over time, the factory's third brake light can become faded, cracked, or may be missing entirely. 5.0 Resto's third brake light lens features a bright red lens, finished with the correct fluting to diffuse the light and for a factory-correct look. Constructed from durable plastic to the correct dimensions with the mounting tabs molded in. Replacing this third brake light is as easy as removing the factory lens and popping the new one into place.

  • Gently lift up on the third brake light assembly to access the third brake light bulbs
  • Twist and remove the bulb harness assemblies from the third brake light
  • Remove the third brake light from the vehicle.

 


Step 3: Remove The Lens

  • Flip the assembly over on a work bench to access the back of the assembly.
  • Using a flathead screwdriver or trim removal tool, release the clips that hold the lens into place.
  • The lens should fall out of the assembly once both tabs have been released.
  • You can use this time to clean up the third brake light assembly.

 


Step 4: Reinstall Component

  • Place the new lens into place and ensure it is fully seated.
