Don't know about the backups but if the stop arm LEDs are connected to the terminals on the module inside the stop arm assembly they will not come on with the lamp check function. Not sure if they can be programmed to. I discovered this when I converted one of our CEs stop arms from standard bulbs to LEDs and used the terminals inside the stop arm.

Thanks for the info on that part of things. That is probably my issue.
