Whoa - 2020 Suburban
Size: 9005+H11
Finally decided to replace the halogens on my 2020 Suburban, and the difference is literally night and day. I do a lot of early morning driving and suffered for 4 years with the halogens. If this is you, stop suffering and upgrade your lights. You will be glad you did. The market is flooded with these LED upgrades, I used AI to help me determine the right fit, best value for the money, and most importantly something really bright. It returned a few options and this was one of them. I can’t speak to the longevity or durability yet, but the results are amazing. The fit is direct replacements, and they look great. Installation was straightforward but did take about 30 mins or so. Basic tools needed for the suburban, 10mm socket, flathead screwdriver, and a panel pry tool was helpful.

Fit 2015 228xi even tho not exact shape as oem
The large clip that has the feet that point out in second position(ballet term, google it so you see what the orientation looks like) fits with much more ease than you’ll think. It won’t hook into its oem place but the top flat squared off part will hook to the interior roof of the that general area snuggly. Spent 1.5 hours trying to bend the smaller ones into a similar shape to oem and then it hit me. The bigger one would probably be large enough to catch the top of the bulb housing. Learn from me. Try the big one.
