Yea I'm gunna wait a little while on the fogs, but I wanted to make sure about the headlights first. But as far as the fogs are concerned I've seen 90% retrofits and figured that was the way to go.

Thanks for the quick response. I found another thread that ended up saying the same, so that's what I'll end up doing. From the sound of thing the projector retrofit seems to be more trouble than its worth in the Sierras.

I just picked up a 2015 Sierra and, like everyone has posted already, the headlights really do suck. I'm new to this whole thing and was looking into picking up the Morimoto 35W 4500K HID's. From what I've read so far it doesn't sound like a plug and play situation, which is fine, but do I need to pick up a separate projector for the headlight? Is it needed or will the HID's manage fine with the ones already in stock headlight? Thanks
