Nice work, great revitalization process, good addition with the silver NJ passenger fleet Arnold. Thanks for sharing the video.
The value of a train is proportional to the happiness it makes. In dollars and cents it depends on what it means to the next owner. In well loved or run PW I have always thought that the LEDs are more stable, perhaps brighter with less voltage. Perhaps a power voltage saving cooler bulb and longer life may be worth it for other reasons. However, the initial cost should be investigated. My brain perceives the LED light to be cold rather than vintage incandescent warm. I personally like the traditional bulb.
I am of the belief that the interchangeability of bulbs does not impact the value unless you have that $4000+ mint NH Lionel EP 5 museum piece ! Lol.
