    Hello all,

    I am looking for a little help.
    I have a Military truck that is 24V.
    We want to add some lights that have high and low beams.
    The bulb we are using is a GE-4811 55W / 110W Bulb.
    Here it is;


    [​IMG]

    ...and below is the back of the bulbs fixture.
    [​IMG]

    As you see there are 3 connections, the center pin is GROUND to the mounting stud, the left is one 55WATT filament and the right is another 55WATT filament.

    SO low beams would be heat up either the left OR right pin and high beam would be heat up BOTH left and right at the same time.

    If I am correct in all the above I now need to control this
    bulb with a particular switch. This switch was originally designed for low and high speed for the trucks heater blower motor.

    Here is that switch;

    Here is the meat of things, knowing I ONLY have this switch to control
    my high and low beams how do I wire it?

    Here is the back of the switch;

    [​IMG]

    "D" position is dead, I can not get continunity no matter what I try.

    "A" and "B" position is one circuit thru this switch.
    "A" and "C" position is another circuit thru this switch.

    It was suggested to me that I;

    Heat up "A" w/ 24V + ,
    Run a wire from "B" to left pin on bulb,
    Run a wire from "C" to right pin on bulb,
    Run a wire from "C" to "B" with a diode in the middle,
    The mounting stud completes ground (like all lights on the truck do)

    The switch is assumed to be heavy enough to handle the power w/o a relay.

    IS THIS CORRECT? IF SO EXACTLY WHAT DIODE DO I NEED TO BUY!

    Everything will be wired w/ 14Ga Prestolite Mil Wire.

    I am a plumber not an electrician!

    I buy lunch to the winning, complete, reply !

    Unless I am missing something, why not just parallel both the high and both the low beams up and feed from the C or B?
    The regular auto way uses this method, the only time it gets tricky is when the low beams are put in series for DTR lights.

    You are missing something. Automotive design work is not allowed on allaboutcircuits. Bill will smack your knuckles with a ruler if you answer this sort of question.

    So I guess if someone posted they just wanted to hook up the same switch and lamps to a 24v battery it would pass?
