921 Reverse Back up LED lights

I bought these to replace the dim halogen bulbs on my reverse backup lights for my 2015 Mercedes GLK350.
The stock halogens were so dim it made it very difficult to see while backing up in dark areas and at night time. So much so that even the camera had a tough time picking up the light. I was able to see more so from the taillights vs the actual reverse light because the stock taillights were brighter than the stock reverse halogen lights.
Replacing the reverse halogens with the 921 was realtively easy and straightforward. the replacement LEDs are significantly larger than the stock halogen bulbs so you will need to finesse the LEDs back into the housing. Was not crazy easy, but not impossible either as long as you take your time.
Reverse LEDs were significantly brighter than the stock halogens and backing up with the camera is like night and day. perihperal lighting as well as range is dramatically improved. No concerns about quick flashing or error light with this swap.
I totally recommend these!

Best quality of life upgrade!

For a CTS-V 3, this was the best upgrade from a functional quality of life upgrade.

Just what my truck needed

I replaced the stock halogen tail light bulbs and it's a big improvement. Turns out I also needed resistors to stop the hyper flashing. They provided and shipped those to me for free, and they are working great now.
