Alrighty now. Got my track sensors mounted under the track(i'll clean it up once I know its working),used RadioS recommended ones. Now I got a matching pair of overhead IR Led RS 276-143 high output ones. Can anyone tell me what power source they use for the overhead light source.? Thanks

I used a 12vdc wall pack and I think a 400ohm resistor for each. I'll have to check for you. You want the LED input to be @ 3 VDC.
