1981 Suzuki GN400
 

Hey guys I have a 1981 Suzuki GN400 and I love the bike it runs great but there is only one problem. The front light does not work. Also it seems that all the lights the blinkers and taillight seem to work better when the light switch is turned on whether or not the headlight works at all. So I am wondering what this might be and if you guys know how to fix it.
