Looking for an Impala switch that handles your headlight beams? The Standard Ignition DS-77 Headlight Dimmer Switch toggles the headlights between low and high beam when you operate the dimmer control. It is a direct-fit replacement for the listed applications, including the 1977 Toyota Land Cruiser, 1981-1987 American Motors Eagle, 1984-1996 Chevrolet Corvette, 1988-1994 Chevrolet C1500, 1988-1994 GMC K1500 and 1994-1996 Chevrolet Impala.
- Copper alloy conductors: designed for superior electrical conductivity with low resistive losses.
- 100% tested: each switch is checked to verify both its mechanical and electrical switching performance.
- Quality control: Standard is a global manufacturer of original equipment ignition products and maintains quality control through every stage, from componentry to the finished product.
- Robust build: a robust design and high-grade materials, backed by decades of research, are made to handle the stringent demands of today's service professionals.
Signs this part may need replacing include high beams that won't engage, headlights that won't return to low beam, or beams that cut in and out when you use the dimmer control. Bulbs, wiring and other circuit components can cause similar symptoms, so diagnose the cause first; if the dimmer switch is at fault, the DS-77 replaces it.
The DS-77 also covers many Buick, Cadillac, Chevrolet, GMC, Jeep, Oldsmobile and Pontiac applications. See the Buyer's Guide tab for the full list and engine details.
