It is typically located on the dashboard or steering column and has various positions or settings for different lighting modes.&nbsp;When a vehicle's headlight switch malfunctions, several telltale signs may arise, signaling its compromised state. Among these symptoms are sluggish or unresponsive switching mechanisms, headlights that refuse to activate or remain off, irregular or intermittent behavior, fluctuations in brightness, non-functional high or low beams, dashboard lighting issues like dimming, malfunctioning auxiliary lights, and overheating accompanied by a burning odor.&nbsp;If any of these symptoms occur, it's advisable to inspect and possibly replace the switch.
