Title: G scale Spectrum headlight LED voltage

Have a couple Bachmann headlights with LEDs that I want to use on a project. What is the voltage range? Also is there any consideration given to re-releasing the two truck Shay?
Thanks,
Dennis B.

Hi, greevesqub,

I find that all you need to do is use a 1000 Ohm resistor in the circuit and that should protect the LeD's up to 22 volts. That is what I do anyway.

some of our electronics experts can be more definitive I am sure!!

Dennis, you are Welcome, have fun with the project! As for the shay can't help, since I am not on the in at Bachmann.

Recent similar queries have generally been that they are not now planning for a rerun, but who knows!! Perhaps the Bach-man or Yardmaster might comment????

Take care,

Bill
