So I bought the LED's that I think alterastro found on e-bay, made a piece so I can put in housing after you cut the back off and it slides in. will use some rtv to keep the LED in place and the housing just fits back in the front clading. here are some pics I hope.
parts
finished
the second part is for the other housing, need to hook up and see if the lights need to be oriented to shine the beam correct.
