Brake lights turn on when you press an automobile's brake pedal. The switch that causes the brake lights to illuminate when you press the brake pedal is located in a number of positions, depending on what kind of vehicle it is. On the 1966 Ford F-100, the switch is pushed in when the brake is not depressed; it illuminates the brake lights when the switch is released rather than when it is pressed.
Location
The 1966 F-100 pickup's brake light switch is attached to the right side of the brake pedal, high on the pedal arm. The pedal operates by swinging from a support bracket. When the brake pedal is not pushed down, the switch is depressed, or closed. When you push down on the brake pedal, it causes the switch to release, or open. It opens a circuit that allows the brake lights to turn on.
Replacement
Replacing the switch is as simple as unbolting the switch from the pedal. Remove the adjusting bolt and disconnect it from the brake pedal. Installing is the reverse of removal.
Adjustment
Adjustment of the brake light switch requires only that you loosen the retaining bolt on the face of the pedal and move the switch back and forth until you have the desired sensitivity.
