Keep your headlamps and dash lighting under your command with the Standard Ignition Headlight Switch / Instrument Panel Dimmer Switch, part number HLS1745. It is a direct-fit replacement for the 2015-2018 Ford F-150, built as an OE replacement to match the original switch's fit, form, and function for easier installation. The part is cataloged as both a headlight switch and an instrument panel dimmer switch, so it appears under both names.
- Copper alloy conductors: Deliver superior electrical conductivity while keeping resistive losses low.
- Direct-fit OE replacement: Designed for proper fit, form, and function, making installation straightforward and replacing a faulty original switch.
- Robust design: High-grade materials chosen to meet the demanding needs of today's service professional.
- Quality control: As a global manufacturer, Standard Ignition maintains complete quality control from start to finish of the manufacturing process.
The headlight switch is the driver's control for turning the headlamps and other exterior lights on and off. The dimmer function adjusts the brightness of the instrument panel lighting. Signs this part may need replacing include headlights or parking lights that won't come on, flicker, or work only intermittently, and dash lights that won't dim or brighten. Bulbs, fuses, and wiring can cause similar symptoms, so diagnose the lighting circuit first. If a failed switch is the cause, HLS1745 replaces it.
