Not sure a rheostat for the house will work on a 12 volt system, but you may be able to find something like a older Ford type healight/dimmer switch---if you can find anything else. Only problewm with a Ford type switch is that it didn't dim the headlamps, but it did dim the dashlights. You could wire your docking lights to the circuit on the switch that controls the dash lights.
