How to Install a Third Brake Light on a Ford Ranger

Laws enacted in 1986 require vehicles built for operation in North America to have a functioning third brake light. Ford mounted the Ranger third brake light at the rear-center of the cab roof, for easy visibility. The purpose of the third brake light is to increase visibility of the brake light system. While many drivers might not have a clear field of vision of the bumper-mounted lights, the third brake light is positioned high enough to ensure that an attentive driver following a Ranger clearly sees the light when it illuminates. Ford recommends examining the lights bi-weekly and replacing any burned-out bulbs immediately.

Instructions

1

Climb into the bed of the Ranger.

2

Remove the two screws holding the third brake lamp assembly to the Ranger's roof, using a Phillips screwdriver.

3

Pull the third brake lamp assembly off the roof. Turn the third brake light socket counterclockwise to release it. Pull the socket out of the lamp assembly.

4

Pull the old bulb out of the socket. Insert the 922 replacement bulb into the socket. Do not touch the glass part of the replacement bulb with your bare hands, as oils from your hand can cause the bulb to burn out prematurely.

5

Push the socket back into the third brake lamp assembly. Turn the socket clockwise to lock it into place.

6

Set the third brake lamp assembly back in position. Thread the screws in, by hand. Tighten the screws with the Phillips screwdriver.
