Features Computer-designed LED halos, compatible with Subaru WRX/STi headlamps Huge increase in brightness, with pure white and brilliant amber output Over 5000 sets installed, with proven reliability. Assembled in the USA   Overview Time for an upgrade! This halo kit is compatible with Subaru WRX/STi 2015-2021 headlights. 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. The switchback version illuminates pure 6000K white color for your parking lights and DRLs, not a cool blue like cheaper products on the market. The halos then illuminate amber when the turn signal is activated. The amber version illuminates amber for your parking lights DRLs, and turn signal. Professional installation is strongly recommended, as the factory headlights must be opened for installation. The halos must be custom-mounted in position using adhesive or beading wire..
