I’m sure this has been covered before but…
Having converted my Bug Mauler to battery, I have to redo the headlight wiring, which must be linked to the no-longer-used track pickups because the light doesn’t work. Anyway, while I’m in there, should I be converting to LED? If so, where do ya get 'em (Radio Shack?) and what kind? Also, what else do I need (resistor, diode, etc)?
Will the light come on almost immediately (before the loco moves) stay on, and be of constant brightness? By Rule Whatever, is the loco headlight supposed to stay on all the time, or only when the loco is moving forward?
And what about the tender “headlight.” I’m guessing it should light only when the loco reverses. So do we put a diode in there?
