2015-2017 Subaru WRX/STi C-Light Switchback LED Boards
Time to upgrade your WRX or STi headlamps! These C-Light LED modules are circuit boards that fit right behind the factory diffusing reflector, illuminating 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, and manufactured in St. Louis, Missouri, to be absolutely the brightest lights physically possible. They are compatible with all factory headlamps: WRX Base/Premium as well as WRX Limited and STi.
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.
Manufactured in USA, the modules light in a pure 6000K white color, not a cool blue like cheaper products on the market. And because they use modern high-power amber chips, rather than traditional LEDs, the amber is even brighter than the white!
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 white, for use at night (parking lights), as well as a full-power white, for use as DRL during the day. Finally, the amber is run at even higher power, making the turn signal easily visible in broad daylight!
Total LEDs: 524 (262 per side)
Real LED Output Power: 13 watts Amber, 10 watts DRL, 5 watts parking (per side)
Inputs: Plug-and-play connector for ground and parking light. T-taps for DRL and turn signal.
Integrated Protection: Full waterproofing and shockproofing, transient suppression, overvoltage protection, thermal shutdown, reverse input protection.
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.
DRL Harness: If you wish, you can add this 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.
