2007 gsxr headlight went out...all other lights work,

Check the wiring on that light. Also check the bulb with a couple of wires to the battery, or swap the bulb left to right to make sure the new bulb is okay.

check the headlight relays ,
Check for possible faulty light stalk switch also. Dash lights may fail with this possible cause.
Check fuses

My passenger side low beam headlight recently went off on me. ... I've changed the bulb again, and changed the fuse just in case, but .... My driver side headlight wire got loose so when i hit a bump at night if would flicker. ... When you notice one side not working (Low or High beam) it could be the module. Headlight replacement

If you give us year--make--model, I'll try to look up wiring diagram?

I drive a 07 Grand Prix and the low beams randomly went out. Could not get them to come back on, but all of the other lights worked (inside, parking, and high beams). found a forum online that recommended replacing the fuse/thing at location #35 in the fuse box under the hood. It worked immediately!! Got the part at Advanced Auto parts for $35 dollars.

check the bulbs just replace the tail light will still work if bulb is bad

See if moisture is in the lens assy.. If so.. you can drill small holes in the bottom of the light to allow moisture to leak/burn out.. Lemmie know

faulty light switch or light control module

your module in the steering wheel is faulty you should get it replaced. you can purchase it at ie Napa for alot less than through a dealer.
