i had the same problem when i first got my X. it turned out to be the headlight switch. you can get a replacement at autozone for under twenty bucks. then just youtube how to take apart your dash if you dont already know how to do it, and put the new switch in. while i was at it, i switched out all of my instrument panel lights (some were burned out) with fresh bright bulbs. since youre gonna be taking apart the dash, its worth doing and only costs a few bucks. before you go to this length though, try checking your fuses and all the other basic stuff. good luck!
