Had my 2007 rubicon unlimited detailed yesterday and now I don't have any headlights. The fog lights work and also my high beams work as they should.
I have had the jeep detailed about 5 times in two years and have never had a problem, If any ideas I would like to hear about them. Peobabily will have to take to dealer for warranty work.

 

I aint got a clue... never had mine go out on me. Did you check your fuse??

 

could be your headlamp relay (just a really big fuse) had one go on a chevy that was 2 years old at the time, can replace yourself but really no way to look at it and see if its the cause or not like on a small 15 or 20 amp fuse... dealer should be able to tell you if that's blown or not.. may not be a warranty covered item but doesn't hurt to at least have them diagnose it

 

+ 1 for th relay , its a 87/87A type


should look like this , it switch power from low to hi beams

 

I think your JK is just mad you don't detail it yourself.
