Help, help, good people! Directional headlight outputs are from the Dallee sound/reverse board. The headlights are very dim at the track voltage necessary for low speed operation but the brightness does vary with track voltage. Anyone have an idea as to how I can get decent headlight brightness? A simple LED with a resistor in series? I don't want to have to do too much experimentation because getting at the rear headlight involves the non-trivial exercise of removing the cab and then the cab floor.
