i searched this already and came up with 0 results. what is the head fuse and what does it do? i can't find anything explaining them in my manuel.

Year, make, model? First guess would be head lamps....

i thought that to at first but both fuses can be removed and the head lights still work. as for the year make and model 80 gl 1600 the fuses say head upper and lower my 90 legacy also has these fuses. i actually removed both the fuses started up the engine and everything works that i can think of checking
