A headlight switch routes power to the headlight circuit when the driver turns the lights on or off. Signs this part may need replacing include headlights that won't come on, flicker, work only intermittently, or won't shut off. Bulbs, fuses and wiring can cause similar symptoms, so diagnose the circuit before replacing the switch. If a worn original switch on the 1987-1993 Ford Mustang is the cause, the DS-340 replaces it.
