If you have a momentary switch in the column, you will need a relay to hold the high beam.
There should be a switch to turn on the lights, that is the middle and end filaments ( one being ground ) then a wire is run from the other filament to the relay which is a latch once on, latch once off or Flip Flop type relay. That should be your high beams.
Warren, how long has this been like this?
