Simple to install, way easier then expected. I marked the OG adjuster screw before I transfered it to the new housing. Wish I could share a video to show how they are brighter then the headlights.

Bought these fog lights for my 2011 sierra, easy to install, however they didn't appear to be any brighter than the stock ones and they also fit very loosely (close to an inch of free movement, visible bouncing when driving). Overall very disappointed with them.

The product is great overall, light up nice. Though they did fit on the loose side shake a lot on a bumping road. I was able to correct this myself

Expected more brightness

After lots of research I settled on these to replace my stock fog lights. Definitely worth the money! I would recommend replacing the mounting clips, as mine were quite loose after removing and replacing. Otherwise very straightforward install. Lots of light! Easily brighter than stock low beams and a good pattern.

I didnt like it not very brigth

First off if your truck didn't come with any fog lights like mine did, you don't have the clips it takes to mount these because they reuse the factory clips that hold in the stock fog lights. So since I didn't have the clips, I had to buy them. Not a huge deal except these lights require an adjusting clip which again, since I didn't have factory fog lights, I didn't have that either AND they so not exist as a separate item to purchase. GM dealerships couldn't get them, Auto parts stores couldn't find them. You cannot buy them individually. I had to buy factory fog light housing because those adjusting mount clips are only available with the housings. More money. Not to mention the wiring harness and fog own light controller swap with the fog light button I had to do. But I knew about that and was prepared so that's not a downfall to the lights themselves.
Once I finally got them in and wired up, it was time to adjust them which is super easy with that adjusting clip. Once I got them adjusted I went outside to see how they project down the road aaaaaanddd.....I get like 20 feet of projection. It will probably help in blizzard conditions or a super heavy rain where all you are looking for are the lines of the road directly in front of your vehicle. But aside from that, not a whole lot of added benefit other than sexy style points. Disclosure, I'm no mechanic. Not a professional fog light adjuster so it's very possible I don't have them adjusted right but I do know that if I adjust them higher then where they are now, the light barely touches the ground so obviously that's not useful. I feel like I have them adjusted where it's the further projection while still getting enough light on the ground to light up road lines.
In summary, good looking, but not $200 worth of light. Not even close. Was an ass load of extra work and expenses for not a huge benefit..
