Standard Ignition Headlight Dimmer Switch P/N:DS-78
Standard Motor Products
Standard Ignition DS-994 headlight dimmer switch for the 1997-1999 Cadillac DeVille and other vehicles switches the headlights between high and low beam. This Standard Ignition switch bolts on and works on a 12-volt circuit.
A failing dimmer switch can leave the headlights stuck on one beam, keep the high beams from coming on or make the lights flicker as you move the control. A burned-out bulb, a blown fuse or a damaged connector can be behind these signs too, so find the cause before you buy a switch.
The 1997-1999 Cadillac DeVille, the 1996-1999 Cadillac Eldorado and the 1997 Cadillac Seville all take this switch.
