mbinsewi You get 15 of them for the $8.
If you want a US Ebay seller, it's 30 cents per LED and 3 cents for a resistor. If you are willing to deal with China, less than 10 cents for the pair.

York1 mbinsewi I think it's great. I also buy prewired LEDs from Evans Designs, as well. Mike. If you want some really small LEDs, Evans has very small ones and they ship very quickly. I get what they call pico size (1mm), and they now offer "z" size, about 0.6mm). https://evandesigns.com/collections/hobby-leds/products/chip-nano-pico-leds

The existing bulbs are simply affixed with black tape to a channel cut in each of the lead weights located at both ends. Lots of space. Ended up ordering the 3mm - one day delivery from Amazon. Thanks for the feedback everyone!
Sometimes it's easier to just utilize the lightpipe - albeit trimmed back or untrimmed. And to make the junction between the lightpipe and the LED, I slide a piece of heatshrink over both ends and shrink it for a snug fit. That's where matching the lightpipe and LED bulb is beneficial. The heatshrink also helps to reduce light leakage - especially if the LED is exposed to the cab area - e.g. the front headlight of an F-unit.
And should I need to replace the LED for any reason I can just slide it out of the heatshrink. No ungluing needed.

mbinsewi richhotrain I use 3mm LEDs when I convert from incandescent bulbs. Same here. Ed (gmpullman) turned me on to a supplier that sells prewired 3 mm LEDs. So much easier. Here's the link. I had them in a week. You get 15 of them for the $8. Mike.

Pretty sure the bulbs are nowhere near the shell, there are light pipes front and rear. The sample pictures on the TCS web site show what look to be 3mm LEDs, soldred right to the end of the A4X board replacement decoder, though it looks like there is plenty of room for a 5mm LED.
I use whichever fits best, some locos have smaller bulbs and a 3mm LED drops right in the place the bulb used to be (sometimes needing a little filing of the ridge around the base - this won't hurt the LED). Others, like the older Atlas/Kato RS3s, you have to do some work because they came with long light pipes and a single bulb in the middle. I cut the light pipes back and since there is a fairly large cross section, glue a 5mm LED to each end.
So it all depends. 3mm more common, but some cases a 5mm is fine.

5mm is 17” in HO, 3mm is 10”. Mel My Model Railroad http://melvineperry.blogspot.com/ Bakersfield, California I'm beginning to realize that aging is not for wimps.
Have an Atlas ALCO RSD 4/5 (HO) that I put a non-sound decoder in years ago but now am putting in a new decoder that has sound. Wondering if at this time I should also replace the front and back bulbs with an LED version, assuming they exist. If so, any recommended ID number or size you would suggest I go with? Or, should I leave well enough alone for now?
