hey thanks for the response, i appreciate it. PnP would never go that route, I have Matsushita Gen4 ballasts in my weak a** projectors now, much brighter but not great output or spread. Probably gonna go full retro, but for now just get the lights and go from there. Just having a hard time seeing if the Depo lights have access like the TYC. Everybody says both are great so.... If anybody has a pic of a 00-06 Depo projector headlight back(nobody shows the back of those lights, need to know if they have access to do retro or add HID lights like the TYC's do) IF ANYBODY HAS A PIC OF THE DEPO PROJECTOR LIGHTS FOR THE TAHOE WOULD BE GREATLY APPRECIATED. thanks for the pic. Pic of my HID's in my Halo projectors, little close but shows how much brighter HIDs are.
