Diode Dynamics has established a benchmark for LED bulbs through a history of innovative solutions crafted to achieve a truly enhanced performance. With advancements in technology, we are thrilled to once again redefine the standard. Allow us to introduce the SL2 and SL2 Pro LED headlight bulbs! Our latest offerings have been meticulously designed as a simple, direct replacement for your GMC Sierra 3500's headlight bulbs, bringing a significant boost in output in a sleek and efficient package. Featuring Next-Generation TST Technology, the SL2 Pro boasts new thermal separation technology (TST) LEDs. Unlike traditional LED chips, TST LEDs have top-mounted electrical connections, freeing up the entire bottom surface to effectively dissipate thermal energy away from the LED. This reduces thermal resistance and enables the SL2 Pro to run at higher power levels than other LED bulbs without sacrificing focus.
