I personally have no problem with LEDs, but feel that it ia absolutely essential that we achieve some degree od standardisation from the beginning.

This should cover the colours and locations of LEDs, for instance red for main power, green for Rx and yellow for failsafe all in a standard location maybe centre rear of the robot.

Surely the FRA could produce a simple stripboard schematic that we should be working to and list were each LED/lead should be connected. Without some serious uniformity of this standard it is likely to achieve very little and maybe throw in extra risk by creating complacency, yet with just a little more thought and careful regulation it could be a major aid to safety.
