The headlights on my 08 wrangler just went off the other night. First it was only the low beams that didn't work. They driving lights in the bumper worked and the high beams worked. Then everything worked fine the next day. Last night the low beams and high beams stopped working. Later they started working again. I do not see any loose connections anywhere, Anyone have any thoughts?

 

Are all the bulbs affected of the stock configuration/wattage?

 

They are all the stock original bulbs. I do have windshield lights that I have wired through a relay to a seperate fuse box that I have had for years. I only use them when I am off road and haven't used them in quite a while. They are not connected to the headlight system in any way

 

Maybe it's an issue with the headlight switch since it affects both the headlights and fog lights. Perhaps a short in the switch or some miscommunication with the switch and CANBUS? Good luck!
