I bought these for my 2018 Wrangler JLU. Install was fairly simple, however I did not use the provided instructions. I found a video online from CJ Pony Parts that explains it real well. The only thing not mentioned in the video is that in order to get the new bulb to seat in far enough to rotate into a locked position, you must remove the white gasket that was under the factory halogen. Once I did that, install was a breeze.
