Signs a headlight switch may need replacing include headlights that flicker, cut out or won't come on, or a switch that feels loose or won't stay in position. If a worn or failed headlight switch is the cause, the DS-148 replaces it. Bulbs, fuses and wiring can cause the same symptoms, so diagnose the lighting circuit before you replace the switch.
