I'm assuming the bulb you are try to replace is of the incandescent variety. First thing to determine is if the bulb is running on A.C. or D.C. If it's running on A.C. voltage, it becomes a bigger issue. L.E.D.'s want to run on D.C. not A.C. Next, you would have to determine what D.C. voltage the bulb is running at. You would need to install a current limiting resistor in series with the L.E.D. or it will fail as soon as voltage is applied. You might want to call Carver as they might have a conversion kit for this unit.
