Switch cleanly between high and low beam with the Standard Ignition Headlight Dimmer Switch (P/N: DS-50). This dimmer switch directs battery power to the high- or low-beam filaments, and it drops in as a direct-fit replacement across a wide range of vintage Ford, Jeep, Lincoln, and Mercury vehicles — including the 1948-1952 Ford F-1, 1950-1956 Ford Country Sedan, 1955-1956 Ford Fairlane, 1965-1969 Jeep Wagoneer, 1967-1969 Jeep Jeepster, 1949-1954 Lincoln Cosmopolitan, and 1950-1955 Mercury Monterey. See the "Vehicles it fits" section for the full 68-application list.
- Copper alloy conductors: deliver superior electrical conductivity with low resistive losses.
- 100% tested: every switch is verified for both mechanical and electrical switching performance.
- Robust design: high-grade materials built to meet the demands of today's service professional.
- OE ignition expertise: made by a global manufacturer of original-equipment ignition products with quality control from componentry to finished product.
Signs the original may need replacing include beams that won't switch between high and low, a switch that sticks, or intermittent beam operation.
