Component compatibility depends on the selected bulb base, dimensions and electrical interface. Match these requirements to the intended installation.

The HP24 Switchback bulb is compatible with any dual-filament 1157-size front turn signal bulb with a clear reflector lens. Bulb Size: 1157 Application: Front Turn Signal Electrical Compatibility: Requires hyperblink fix (resistors or flasher)

By using this dual-filament design, along with the embedded digital timing circuit, you can upgrade this look: the HP24 lights up in a 6000K cool white color when your headlights are turned on, and flashes amber when the turn signal is activated. When you switch the turn signal off, it “switches back” to white. This allows you to upgrade your front end to an all cool white appearance, while still keeping your turn signal functionality. The HP24 bulb is only suitable for vehicles that have a clear front turn signal reflector lens.
