So I have a 2018 Wrangler JL and it came with the halogen lighting package. Like most you I changed them to LED, headlights to after market LEDs and the fog lights to mopar LED fog lights. The fog lights worked for about a week and then stopped working. I checked the fuse box and the fuses don’t seem to be blown. Any suggestions?

I had the same issue. Apparently it burns out the LEDs running them on halogen settings. I've been trouble shooting mine all day and finally pulled a foglight from a second bumper, plugged it up...and voila, Fog lights. Plug the installed one back up and nada. Well, so much for "I just plugged mine up and they worked". That'll be $350 please

I just had this happen on a 2018 JLU Sport. Fogs worked for about a week, then just cut off and won't come back on. I didn't realize there was an LED fog setting in the Tazer. I went to enable that setting, and they still won't come on. I'm guessing the fogs are toast being I hadn't changed the setting prior. Major bummer.

So many folks have had great experiences with this being plug and play, but it must not be the case for all situations. In my case, 2018 JLU Sport with halogen headlights and fogs from factory - the fog lights came from a 21 JLU Rubicon with LED factory.

Still trying to find a way to ensure the fogs are truly dead, but this feels like an unfortunately expensive mistake right now.

Check for power at the lights. Make sure the BCM didn't just freak out and cut power. These lights can act weird.

For sure - I’m going to check this weekend hopefully. I still have my halogen fogs I can pull and plug in to see if they get power as well. Thanks for the reply!

I did the same thing but have now changed the code and installed a new set of led fogs so all is good. Does anyone know if there is a way to repair the first set of lights by replacing an internal fuse, etc. or are they trashed?
