Put headlight, high/low beam, and turn-signal control back at your fingertips with the Standard Ignition Combination Switch DS-666. This multi-function switch mounts at the steering column and drops in as a direct-fit replacement for the 1991-1994 Chevrolet Cavalier, handling your headlights, dimmer (high/low beam), and turn signals from one stalk-operated unit.

  • Three functions in one: serves as the headlight dimmer switch, headlight switch, and turn signal switch for the listed application.
  • Stalk-operated control: operates the headlights, high/low beam, and turn signals from the steering-column stalk.
  • Signs it may need replacing: turn signals that won't cancel or flash, headlights that won't switch on, or a high/low beam that won't change when you move the stalk — if a failed switch is the cause, this replaces it.

Because a no-signal or no-headlight condition can also stem from wiring, bulbs, flashers, or fuses, diagnose the cause before replacing. This is an aftermarket replacement combination switch.
