I’m impressed by the quality, look, packaging, and functionality. I don’t normally buy things that haven’t been reviewed by anyone but took a chance with these because I hated my factory halogens and boy am I glad I took the chance. So, since this is supposedly the first review for these, I’ll try to be thorough.First off, they’re exactly what I was looking for! I found it pretty difficult to find quality parts for a 2018 JL 4 door rubicon (JLUR), but these are definitely quality. They plug right into the factory halogen light housing and have not thrown any codes. EXACTLY what I was looking for!Second, I would give the install a 3/5 on level of difficulty. It’s not extremely challenging if you’re a DIY type of person but you do have to unbutton just about the entire front half of the fender. Took me about three hours total, but the wife and kids are home so I wasn’t in a real hurry anyway! I started on the passenger side which took way longer because I stopped to take some comparison pics/videos. The drivers side went considerably quicker. Note, there are no instructions - but let’s be honest, I wouldn’t have read those - so thanks for not wasting the paper! There is a large black plastic piece that screws into the factory assembly and you need to transfer that piece to this housing. I found it easiest to take that off first, then remove the factory assembly from the bumper. Reinstall is the reverse. Install these new lights first, the re-install the black factory piece.Finally, NO! You do not need any additional transmitters, diodes, adaptors, ballasts, regulators, conversion kits, etc. (what even is all that stuff anyway?). You simply pull out the factory halogen bulb and plug these suckers right into the halogen bulb housing. Couldn’t be easier!
