Get your 2007-2013 GMC Sierra 1500’s SL1 LED Headlight Bulbs here: https://www.diodedynamics.com/low-beam-led-headlight-for-2007-2013-gmc-sierra-1500.html
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.

Where can I get that same headlight for my truck same one *?????
You do not have to remove that trim pile
Who are the MORONS at GMC that designed the headlights?? Moron!
After all that, I'd replace all the bulbs whether they needed it or not.
Why would you make it so that the connectors could be installed backwards?
Thank you. I was able to replace mine by just poping off the driver's side trim and move it enough to remove the light fixture.
I didn't have to remove the middle whole trim.
Fuck GM for this. I had a 2001 GMC Sierra that took literally two minutes to replace the lights. My 2009 is such a pain in the ass to replace lights.
If i have already managed to change out the halogen h11 lamps several times without dismantling anything, why would i dismantle the upper shroud and remove the lamp assy?
Just started on my 2009 truck doing some mods but that bottom trim piece beneath the grill will not come off anyone got tips?
