More than likely it is the high beam switch. I have two 01's with no low beams the switch was not making contact for the low position. The contacts are on a spring and the grease for the contacts gets hard so the contacts don't make with the plate. once they star to stick the contacts will arc and burn a little so they wont reach you have to shim out the contacts or replace the switch ( $105) or by-pass that switch altogether. I hope this helps
