Those are fairly large, I'm not sure that LED will fit into the class light. If you've found a small one in say the 3528 LED form factor, I'd like to see it.

No what I am referring to are the marker (red) lights on a tender or even the last diesel in Mu right in front of the coupled passenger or freight consist. Is thee any reason and/or rule that requires these to be lit. It seems to be no since they are not visible since the passenger/freight consist would bloke the view. But there might be a rule.

No. They should be turned off. Those rear marker lights are only for when the locomotive, steam, electric or diesel, is running light, i.e. without a train, or if in helper/pusher service when coupled behind the caboose ( the locomotive then being the end of the train).

Nope. No rule.

John this is the LED that I bought. Guess it isn’t white. But amber. I bought it months ago.
On the class lights discussion, I believe the PRR stopped using class lights sometime before WW2. What looks to be class lights in the traditional location on the top of the smokebox are actually marker lights and should be red. They would only be illuminated at night and for reverse movements when the front of the engine represents the end of the train. Maybe some Pennsy afficianados can chime in in this topic. As a modern steamer the T1 would have marker lights, not class lights, in the front of the locomotive.

Interesting LED, I hadn't seen those. It might actually slide into the class light fixture if you use really fine wire. You will have to insulate the bottom connections. The whole unit is only .1" long and half that wide, it'll be fun soldering four wires to it.

Thats why I haven’t wired them up yet 😅
The size is right, but I don't know how you get four wires onto them and insulate them to fit into the 2mm opening of the class lights.

Ill have to use my #38 magnet wire from Ngineering
