this transformer has 2 indicator lights-one red & one green. the green one goes on when you plug it in. the red one never goes on(bulb is ok). what’s up?
Walter, if nobody responds soon with the answer you can use, try posting your question where it will be sure to get an answer quickly. That would be the Classic Toy Trains forum.

Strckley a guess here as it has been years since I dealt with any Lionel units.
My guess is that it would come on when there is a short circuit. Trucks etc. shorting out when derailed or something left or falling on the track that is short circuiting. Possibly a stranded wire coming loose and touching another terminal would cause this.
Short out your track and see if it comes on, then you’ll know for sure.
Johnboy out…
Your correct the red light is for when you have a short.
…and will only come on when the thermal circuit breaker trips.
