The Diode Dynamics LED board kit replaces factory accent boards in GMC Sierra headlights (2014–2016) with direct‑fit units that provide a brighter DRL and a more visible amber turn signal. Each order includes two sets of LED boards, waterproof drivers and input pigtails. The switchback boards illuminate white for running lights and light up in a brilliant amber for signaling while maintaining OEM alignment and direct replacement fitment.
