Good point. That's how drivers can cope.

Hi Steve! I don't have a copy of that standard but I'm picturing the
red/yellow/green towers on things like manufacturing floor hipot
testers. Have you considered the colorblind user who might not be
able to discern yellow from red, but on a 'stoplight'-like tower, can
at least use the illuminated position to determine the indicator status?

Experts,
I have a client who would like to use a single LED capable of
multiple colors instead of a mutli-lamp light tower that we are
used to seeing.
It can produce the required colors in accordance with 60204-1,
Table 4.
I have read through 60204-1 (machinery) safety and 61310-1
(requirements for visual, acoustic, and tactile signals) and did
not find anything that prohibits the use of a single LED.
Thoughts?
