Take a test light and start with the cables down by the switch
Ignition on you try the incoming then check the outgoing with the gear in
If this works, go back to the bulb and check both positive and ground
connections.
If the trouble is down by the gearbox you could replace the gearbox switch
with a manual swich up front, nice to have at night when the person behind
you don�t dim his headlight too ;-)
