Issue with territory

Hey there guys and girls i know this vehicle isnt a e series but i thought someone here might no how to my issue is to be fixed .
Up till last week the high beams in my territory worked fine and then the other night everytime i went to use it not only did they not come on all the lights died in the ass and went out. So i thought it might of been a fuse issue and just checked all those and there 100% fine so im now guessing my high's globes might be stuffed. If anyone knows what might be the issue or if im right with the globe issue some help would be good thanks everyone.
