43??P direct fit lamps that don't have the LED bullseye
12/19?P with G3.5 globe
19 frosted G3.5 globe
55 lamp for the smoking caboose
51 lamp in the 193 Water Tower
363 for the 455 Oil Derick
Yes I am aware of auto illumination Town & country hobbies and similar offerings but nothing comes close to the real charm of incandescent bulbs for me so if you've got something that's easy straightforward and a direct fit I'm all ears
Don't forget the L452W bulb for the Lionel No. 64 lamp post. Good luck finding an LED replacement for that one!
But when it comes to the 193 water tower - I actually did a really nice job replacing the 51 bulb with an LED. I purchased a 5mm red "breathing" LED. It fit nice and tight into the hollow bottom of the No. 252-11 red lense cap. I'd say it looks brighter, better and now has a more prototypical breathing action
