Does anyone happen to know the voltage bulb that lionel used in their legacy models around 2011? I picked up a SD70M-2 and I know the headlights and rear lights are leds, but the number boards and interior cab light are those small grain bulbs and looking to replace them with leds because they get the roof so freaking hot that it begins to warp. Also I assume they were DC anywhere between 6-12v, but were they DC or AC? Thanks in advance.

I’m taking a wild guess here as I’m an HO guy. I’m assuming that your estimate is correct for the voltage. They should be AC as the rest of the unit is. You could try some inexpensive 5-6 volt bulbs first, and if need be go to 12 volt.
Thanks for the reply, going to give it a shot with leds for ac/dc -6-19v. Looking to stay clear of bulbs altogether for they create way too much heat for the plastic IMHO.
Incandescent bulbs run on AC or DC, they don't know the difference. LED's are a good replacement choice.
