1986 Mercury Cougar tail light/brake light bulb troubleshooting (check in this order):
· Check Fuses
· Check Bulbs
· Check Relay(s)
· Check Light Switch(es)
· Check license plate light bulb and wiring
· Check trailer hitch wiring harness

Most likely its the fuse or a burnt bulb breaking the circuit. Sometimes the license plate and/or the trailer hitch is wired into other circuits and can cause issues in other areas. Sometimes its wires grounding out somewhere on the vehicle. See sources and related links below for bulb information. See owner's manual for location and identification of fuses as well as for bulb replacement procedures.

The tail lights on my 1993 Mercury Cougar dont work. All other lights and signals work including the rear turn singals and the hazards.?
If you have not done so, check the tail light bulbs. The Cougar uses a multi-function bulb, with separate elements for brake lights and directionals. It is possible for one element to burn out, while the other is still intact. To get at the bulbs, pull up the trunk liner in the corners. The bulbs are easilly accessable, and come out with a quarter turn.
