Hi All,
I'm looking into implementing some LED warning lights on one of our new products. However I'm a bit confused about the warning colors of the LED.
I've seen devices with Yellow/Orange/Red and even Green warning LEDs.
I've been reading up and couldn't really find an normative list.
in the IEC 60601-1-6 CCC.4 they say:
Controversial mapping – This is any mapping that contradicts an established convention. An obvious example would be the use of the colour green as a warning indicator. Another would be the flow control on a gas machine requiring a clockwise turn of the knob to increase flow.
[edit]
Seems that the 60601-1 7.8.1 also has something to say about indicator lights
Red Warning – immediate response by the OPERATOR is required
Yellow Caution – prompt response by the OPERATORis required
Green Ready for use
Any other colour Meaning other than that of red, yellow or green
[edit]
So green is obviously out.
I also found an advisory from the FDA advisory, basically stating for lasers they just need to visible with safety glasses on.
Any ideas on this?
