Features Computer-designed LED boards compatible with GMC Sierra 2014-2015 headlights. Two high power LEDs in place of each original white chip. A huge increase in brightness, even in direct sunlight. Adds brighter running light, and amber turn signal. Engineered and assembled in USA. Overview Time for an upgrade! This kit is compatible with GMC Sierra, which has LED accents in the headlights from the factory that illuminate in a white color, for the parking light and DRL. Diode Dynamics replacement LED boards add a brighter DRL and additional amber turn signal for a custom, yet functional look. Your order includes two sets of LED boards, one for each side of the vehicle. Switchback. These LED boards are a direct replacement for the factory ones, but have double the number of LEDs. They illuminate white for your parking lights and DRLs, with a dimmed power level at night. Anytime you hit your turn signal, they light up in a brilliant amber that is even brighter to indicate signaling. While the amber is extremely bright, we do not recommend disabling your factory turn signal. OEM-grade design. At Diode Dynamics, we work directly from OEM data, and use a 3D scanner, to develop precise replacement boards with identical mounting points and shape. Just remove the original boards, and ours will fit directly in place with correct alignment. You'll also see OEM design features, such as high-intensity automotive emitters, wire connectors, and serial numbers for quality assurance.
