Take command of your headlights and dash lighting with the Standard Ignition Headlight Switch / Instrument Panel Dimmer Switch (MPN HLS1743). This combination switch controls the headlight circuit and adjusts instrument-panel dimming, and it drops in as a direct-fit OE replacement for the 2015-2017 Ford Mustang — see the Buyer's Guide tab for engine-level details. It's listed under both names because it serves as both the headlight switch and the instrument panel dimmer switch.
Copper alloy conductors: deliver superior electrical conductivity with low resistive losses.
Direct-fit OE replacement: matches the fit, form, and function of the original for straightforward installation and proper restoration of a faulty headlight switch.
Robust construction: robust design and high-grade materials built to meet the stringent demands of today's service professional.
Quality controlled: produced by a global manufacturer maintaining quality control throughout the manufacturing process.
If a failed switch is the cause of headlights that won't respond or dash lighting that won't dim, this replaces it. Signs the original switch may need replacing include headlights that won't turn on or switch modes, flickering, or dimmer control that no longer adjusts panel brightness.
