with the bike running , use a circuit tester and make sure you have voltage to ground on the low and high beam , if not use a seperate ground , like the frame of the quad , if it then lights up , then you have a bum ground wire , if still no voltage , check the wires at the switch , if its the switch , junk it and just install a couple of toggle switches , OR just rob power from the taillight and run it forward . either way easy fix .

If your taillight works the headlight should too. You are sure its not the bulb. Check it with a meter like he said and connections. 3 wires on the headlight. 2 are power for low and high and one is ground.
