A headlight switch sends power to the headlamp circuit when you switch it on. Signs it may need replacing include headlights that won't come on, flicker, or work only intermittently. Because fuses, bulbs, wiring and grounds can cause the same symptoms, diagnose the circuit first. If the switch is at fault, the DS-651 replaces it. If you need a Blazer switch for a 1995-1997 Chevrolet Blazer, this part is listed for those model years; see the "Vehicles it fits" section for the other listed vehicles.
