### ⭐⭐⭐⭐⭐ Great replacement for factory bulbs to led bulbs and with built in resistors it resolves hyper flash
*by R***. on December 20, 2025*

Great to find these to resolve my hyper flash I have been tolerating since converting my 2007 Chevy Tahoe over to LED last year. You have to do front and rear turns on each side to resolve the hyper flash. I did one side and it flashed normally. The other side still hyper flashed until I did both the front and back on that side. The back is really easy, two screws on each side then gently prying the push in plastic closest to the rear fender and housing comes right out. The front is much more involved. Remove top 10mm bolts on light housing and 10mm bolts on the top of the grill to loosen it allowing the headlight housing room to come out, then front of fender liner on each side 2 7mm bolts and a few push clips then a 10mm on the borrow of headlight housing and 2 10mm bolts just inside the fender liner and remove the plastic bracket that supports the front ‘bumper’ to loosen it up allowing the headlight housing room to slide out. Then once bulbs are change reverse the process. Note: the headlight housing is in there pretty tight and requires some gentle work and prying, don’t forget it is plastic so go easy on it. I like the fact that the include built in resistors so I do not have to manually install them in he circuit. Much brighter than factory bulbs that came on this 2007 Tahoe. I would recommend while you are in just do all the bulbs at once - daytime runners, turn signals, side markers and high and low beams since it is a big process to get to the back of the housing. Same with the rear change out side markers, turn signals and brake/runners. Red leds are best for rear and amber and clear where applicable on the front and of course white bulbs for reverse and headlight bulbs.
