Hello Holly, In the RIA 15.06-2012 is mentions a required status light when the servo drives are enabled. I can't recall it's location in the standard right now. There are no safety requirements for a status light to notify of operation mode or faults, but it is a good idea. If you have any other questions please let me know. Thanks, Johnathan

Operating mode and status indicator requirements are spelled out in NFPS 79 and ISO 60604-1. Operating modes should be clearly indicated. Stack lights is one method. Hope this helps.
