AFAIK Tomar makes only markers with LEDs installed. For class lights you have to add your own but the specific LED is readily available from the same manufacturer or from an electronics supply like Digikey. They are 2mm ceramic LEDs made by Lumex. I know you can get the housings from Lionel and Precision Scale, I suspect MTH as well.

Kind of related to this topic; I seem to recall a wiring diagram that showed how to have front and back classification LED's that alternately lit up depending on engine direction, powered by the reversing +/- polarity power being fed to the can motor. Can't seem to find this info now, anyone have a copy or a link to the thread?

What would be even better would be 2 color LED's that switched from red to green, and back, depending on direction of travel. Anyone know how this could be done, simply, using motor polarity? Would the above TAS schematic work with power from a can motor, maybe with a diode in each wire to control which set of LED's lights up?

Here's a schematic of when I did lighting like this, I used the directional headlights and not the motor voltage.  Motor voltage is only there when you're moving, the headlight is there all the time.  You need common anode three-wire LED's for this scheme, but it works very well.
