Why do my brake lights not work on 1992 Oldsmobile cutlass?

Brake light failure happens from a variety of problems, such as burned out bulbs, a short in the headlight wiring or a blown fuse. You can tell if the bulbs are out by a rapidly blinking turn indicator, a blown fuse by checking the fuse is the panel on the side of the dash, and check if its a short circuit by using a volt reader in the light socket.
