Switch between low and high beams at the dimmer control with the Standard Ignition Headlight Dimmer Switch, part number DS-352, the switch that selects which headlight beam is on. It fits many vehicles, among them the 1987-1991 Chevrolet Blazer, 1989-1991 Chevrolet R1500 Suburban and 1989-1991 Chevrolet R2500 Suburban, as a direct-fit replacement for the listed applications.

Signs a headlight dimmer switch may need replacing include high beams that won't engage or won't switch off, headlights stuck on one beam, or headlights that work intermittently. Wiring, bulbs and other components can cause the same symptoms, so diagnose the headlight circuit before replacing the switch. If a failed dimmer switch is the cause, the DS-352 replaces it.
