Take control of your exterior lighting and dash brightness with the Standard Ignition Headlight Switch / Instrument Panel Dimmer Switch (HLS-1641). It installs as a direct-fit replacement for the listed application — the 2008-2010 Saturn Vue — combining two driver controls in one unit. As the headlight switch, it routes power through the headlamp and parking/marker lamp circuits; as the instrument panel dimmer, it varies the brightness of your gauge and dash illumination.
Signs this switch may need replacing include headlights or parking lamps that won't turn on or work intermittently, or dash lighting that won't dim or brighten. If a worn or failed switch is the cause of those symptoms, this unit replaces it — diagnose the circuit first, since wiring or bulbs can produce similar signs. This part is listed under both names because it performs both jobs.
