Alright guys, I have gone thru a ton of pages trying to understand all of this... It's making my head spin. I have a '15 LTZ with the s*itty Halogen Projector headlights and they suck. What exactly do I need, to get more light and a brighter pure white light ( not the piss yellow ), I hate the blue colored light so I was thinking 5500k. If someone can tell me everything I need... my second question is exactly how hard is it to install? I'm sick of the crappy lights that should be WAY better than they are. Came to Lubbock tonight, and on the way to the hotel on the pitch dark highways, the light just ISN'T the way it needs to be. I'm sure this is simple stuff to understand, but as I have never done this I would appreciate a little help, maybe a little step by step.
