wiring headlight help

Maybe I am missing something here, but if you used 1 switch to several relays, (say 3) I dont see what the problem is....
You could fuse the load side of each relay, and if something shorted, it would blow that fuse....
To protect your switch, you could put a low amp fuse in each relay (solenoid side) and if it shorted, that would protect your switch...
