Time for an upgrade! These C-Light LED modules are circuit boards that fit right behind the factory diffusing reflector. The Switchback option illuminates in an extremely bright white, as well as a brilliant amber. Don't be fooled by other options on the market: these LEDs have been designed from the ground-up for this application, and assembled in St. Louis, Missouri, to be absolutely the brightest lights physically possible.

High output, clean appearance. The custom-designed LED modules replace the factory bulb or single LED, illuminating with a much higher intensity. With our proprietary high-density "HDLED" technology, these modules are populated with over 500 LED chips, which are then coated by a diffusing gel, resulting in a perfectly uniform light when turned on. When it's off, the diffusing gel hides the chips, resulting in a clean, OEM appearance.

Choose your look. These C-Lights are available in two color options: switchback illuminates with a dual color function, providing a pure 6000K white color for the running light, along with a bright amber for turn signal. The all-amber version illuminates with amber output for turn signal as well as the running light, for a distinctive look.

Constant-current power. To power the modules efficiently, your order includes two custom-designed drivers, which feature transient voltage suppression, reverse protection, and a switching driver for extremely high reliability over time. And here's what really makes this product shine over the competition: with an embedded microcontroller, the drivers utilize multi-stage PWM dimming, to allow for a half-brightness DRL, for use at night (parking lights), as well as a full-power DRL during the day. Finally, the amber turn signal is run at even higher power, making it easily visible in broad daylight!

Wire it up. Wiring instructions are included with your order. You will need to use the included T-tap connectors to connect the drivers to ground, parking signal, and turn signal on each side. Another wire is included for DRL connection. You can tap this into your DRLs to have the C-Light come on as a DRL alongside your factory DRL bulb. If you wish, you can add the DRL Harness to your order. Fully plug-and-play, this harness will disable your factory DRL, and power the C-Lights instead. Your high beam will still work as normal.

Professional installation is recommended for this product, as the headlights must be opened. However, these lamps are substantially easier than most to work with, so we do recommend watching the installation process yourself, by viewing our video.
