Installed H11 Philips HIR bulbs. Easy clipping of the top tab.
Turned the lights on after installing one, and the HIR was apparently brighter that the stock 9005 Sylvania.
Went to install new 3000k led fogs, and found that the 4190 listed is incorrect. I have H8s in there. Returned those and ordered proper sized replacements. I could not find H8 on the fog light lens, nor any size.
Finally, i towed my pop up camper with it for the first time, about an hour each way between home and the campground. OE trailer brake control installed worked fine. Had to up the gain to 6.5, which seems a little high for a 10' box pop up. But it towed just as well as with my 2010 Suburban with aftermarket tbc wired in. Hooking up was a bit easier using the rear camera (burban had none).
