Latest Release Legacy M1 Marker Light Issue

No issues with mine. I got the M1 #6871  Just send it to Lionel, they will fix it quickly.

9 times out of 10, it’s a connection issue with class/marker lamps. Sometimes the way the factory has to bend the tiny harness can cause a lead to come undone at the LED. If you’re not in the warranty voiders anonymous club, you’ll have to send it back to Lionel for repair,…..there’s no pixy dust we can recommend sprinkling on the failed light to make it work. Lionel’s newer smoke motors are notoriously noisy. Ask for a replacement, and it’ll be just as noisy……Hooray for low-bid vendors!……most of us swap the motors out for MTH motors, but you’d need to be in the warranty voiders anonymous club, and know the secret squirrel handshake,…….😁

Same problem with my new Vision Line Triplex, one of the class lights is out.  I know it's a solder connection because I can pinch the wire right below the LED and the light comes on.  I'm going to try to get a new harness from Lionel to fix it and not have to ship the whole locomotive back to them.
