Standard Ignition Headlight Switch,Instrument Panel Dimmer Switch P/N:DS-177
Keep headlight and dash-light control right at your fingertips with the Standard Ignition switch DS-268. It is a direct-fit replacement for many vehicles, among them the 1987-1996 Ford F-150, 1987-1997 Ford F-250 and 1991-1994 Ford Explorer. This headlight switch is also listed as an instrument panel dimmer switch.
The headlight switch sends power to the headlamp circuit when you turn the lights on. Because this part is also cataloged as an instrument panel dimmer switch, it lets you adjust how bright the dash lighting is.
Signs this switch may need replacing include headlights that won't come on or that cut in and out, and dash lights that won't dim or stay dark. Diagnose the lighting circuit first. If a failed switch is the cause, DS-268 replaces it.
