This video demonstrates the installation steps of Diode Dynamics SL1 LED Headlight bulbs on a 2008 GMC Sierra 1500. The SL1 LED Headlight bulb is engineered to perfectly mimic your Sierra's stock beam pattern while being FAR brighter and more focused. The result is dramatically upgraded visibility, and a much more modern look, thanks to the 5700K "cool white" color temperature.

Unlike generic LED bulbs, the SL1 features an advanced optical design that allows for increased light output with zero added glare. As shown in this installation video, the SL1 LED Headlight Bulb is 100% plug-and-play, with NO splicing or wiring needed. The bulb and driver tuck neatly inside the 2008 GMC Sierra's factory headlight housing without any modification.


We proudly manufacture the SL1 right here in the USA. And as with all Diode Dynamics LED lighting upgrades, the SL1 is backed by a 3-year warranty.
