Standard Ignition Headlight Dimmer Switch P/N:DS-78
Switch between low and high beam with confidence using the Standard Ignition DS-68 Headlight Dimmer Switch, built with copper alloy conductors and tested for switching performance. It fits many vehicles, among them the 1966-1978 Dodge Charger, 1988-1990 Dodge Dakota and 1962-1981 Chrysler Town & Country, and is a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list.
A headlight dimmer switch selects which headlight beam is powered. It lets the driver toggle between low beam for traffic and high beam for open, dark roads. If a worn dimmer switch is causing your beam trouble, this unit replaces it.
Signs this switch may need replacing: the headlights may stay stuck on high or low beam, or the beams may not change when you operate the switch. The lights may flicker or cut out when switching, or the high-beam indicator may not respond. Wiring, bulbs or connectors can cause similar symptoms, so diagnose the circuit before replacing the switch.
