I like the light and look of these but have also struggled with the binding. I therefore unclip the eye from the motor. They stop moving when you do this but stop binding!
I only power the access point to my loops. The exit point is floating with a dummy motor and I leave the eye loop for the lantern in place on these. They are thrown by flanges as the train leaves. For some reason these lanterns never bind!
I have a few spring loaded points that always send trains the same way. These have lanterns made from the earlier pre EPL LGB design which are set and cannot rotate.
I do have one PIKO motor, add on switch unit and lantern, which looks wonderfully thought through. I have never used this outside though. After the comments made in this perhaps I had best leave it!
