You probably have a bad fuse. The little box you checked underneath the headlight is the Xenon ballast, which enables you to use Xenon lights as your main headlights. You tested that box so, your ballast is fine.

Check Fuse #39 which is the low beam headlight fuse.

atcually it was fuse number 61 which 61 and 60 control either left or right headlights to come on. but i checked the fuse thanks to you and used the spare fuse to replace it thanks a lot though you helped and one last thing, on the right headlight theres the auto levelizers on the headlight well, when i took the headlight off the car and disconnected it there was this bulky 12V battery connected bellow the xenon bulb but above the xenon balast which i think controls the levelizer (pretty sure) well i took it apart because i thought thats what was the problem well i put it back in and now when i turn the headlights on that right headlight will only stay on for 40 seconds then shut off by itself i can get it to turn back on but i have to swith the headlights all the way off then turn them back on again and then that right headlight shuts off in 40 seconds again, did i do something wrong or is there another fuse i should change, im not sure if its a timer or some sort of thing?
