Take charge of the headlamp circuit in your classic Ford with the Standard Ignition Headlight Switch DS-188. This switch sends power to the headlights when you turn them on. It is a direct-fit replacement for many vehicles, among them the 1975-1976 Ford F-150, the 1965-1976 Ford F-250 and the 1966-1977 Ford Bronco; see the "Vehicles it fits" section for the full list.
- Copper alloy conductors: Deliver superior electrical conductivity with low resistive losses.
- 100% tested: Every part is checked to verify both its mechanical and its electrical switching performance.
- Controlled production: Standard Ignition is a global maker of ignition products. It maintains complete quality control across the manufacturing process, from componentry to the finished product.
- Built for the technician: The switch pairs a robust design with high-grade materials. It is backed by decades of research and development focused on what service professionals need.
Signs a headlight switch may need replacing include headlights that won't turn on, lights that flicker or cut out intermittently, or erratic switch operation. Bulbs, fuses and wiring can cause the same symptoms, so diagnose the circuit before replacing the switch.
