What is the wiring for one headlight on a fourwheeler that has high and low beams.
one terminal on the bulb is common to both low and high beam. that will be the ground. the other two are the hi and low beam supply .take a test light and see which two of the three wires has power to ground . once the two hot wires are identified , the third wire will go to the common terminal on the head light bulb. take the other two and see which is hi and low by switching the switch and connect to the bulb . test the light before reinstalling it if there is no power at the wires than the problem is somewhere else
Year? Make? Model# ? If it has 1 headlight with a high low beam, the bulb has 2 filaments.
