Standard Ignition Headlight Dimmer Switch P/N:DS-70
Keep control of your low and high beams with the Standard Ignition Headlight Dimmer Switch DS-79, the switch that moves your headlights between low and high beam when you operate the dimmer control. It fits many vehicles, among them the 1978-1985 Chevrolet Impala, 1978-1983 Chevrolet Malibu and 1982-2002 Chevrolet Camaro, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
Signs a headlight dimmer switch may need replacing include high beams that won't come on or won't switch off, headlights stuck on one beam, or beams that change only intermittently. If a worn dimmer switch is the cause, this part replaces it; diagnose the headlight circuit before replacing any parts.
