I'm hoping to fit some LED's into the point lanterns (turnout lantern) on some Trix C track points and would like to power them directly from the track.

I thought about using 18 volt or 24 volt LED's as they can handle the 15 volt power supply I will be using.

Question is, will they be damaged if I accidentally connect the LED's the wrong way around? Will an 18 volt or 24 volt LED be able to handle the 'reverse voltage' for a while until I can change the wires over?

That depends on the "LEDs" - some include a bridge rectifier, so reverse voltage is not a problem for those.

If you run digitally: the voltage will reverse a few thousand times each second, quicker than you can change wires ...
If you run analogue: the voltage will reverse whenever you change the direction of your trains ...

I was going to use them with digital track, so it looks like it won't work.

Are there any manufacturers who make LED's with bridge rectifiers?
