What tests have you done? Could be wiring, switch, bulb. Start with the obvious and check your bulb. Then check for voltage when the bike is running. Make sure no wires are broken. Should show A/C voltage between the green and black or the yellow and black wires at the headlight depending on what position your switch is in when it is running.
