Pop-up headlights in a 1986 Pontiac Firebird receive their power from the vehicle's electrical system. The power is supplied through a relay, which is controlled by the headlight switch. When the headlight switch is turned on, the relay closes and allows power to flow through the headlight motor.
Headlight Motor
The headlight motor is responsible for raising and lowering the headlights. It is a small electric motor that is connected to the headlight assembly. When power is supplied to the motor, it turns a gear that moves the headlight up or down.
Limit Switches
Limit switches are used to prevent the headlights from moving too far up or down. They are located at the top and bottom of the headlight assembly. When the headlight reaches its upper or lower limit, the limit switch will activate and turn off the power to the motor.
Headlight Switch
The headlight switch controls the power supply to the headlight motor. It is located on the dashboard of the vehicle. There are three positions on the headlight switch: off, on, and parking lights. When the headlight switch is turned to the on position, the headlights will raise up and turn on. When the headlight switch is turned to the parking light position, the headlights will remain lowered but the parking lights will turn on.
Headlight Relay
The headlight relay is a small electrical switch that is used to control the power supply to the headlight motor. It is located in the engine compartment of the vehicle. The headlight relay is activated by the headlight switch. When the headlight switch is turned on, the relay closes and allows power to flow through the headlight motor.
