headlight issue

[RANDAL]

Hey Guys having some trouble with my headlights on my Jimmy. coming home from work last night the passanger low beam headlight went out. It works on the high beams so I'm guessing the bulds low beam went out so I switched them to high on the way home all 4 were working when I left my work but when I got home the high beam light was out (the inside light)and only the low beam bulb was working on high I hope this isnt confusing to anyone. if you can help that would be great.

Thanks
