interesting safety aspect there... I think that it might be interesting to see if the whole hat could glow a certain colour depending on conditions rather than just the light. howman

I think this is an interesting idea, I am not sure if you could miniaturize all the gas sensing electronics to make them fit in the light, but even if you couldn\'t and the gas sensor still had to be worn like it is now, the light changing would remind the miners to look down at the readout to see what the level is.

original and careful idea lili

not cool if you are trying to get out of a gas-filled mine and still have to put on that panicking red light everywhere. the application of this 3-color code for gas safety would be better if the helmet main led stood white all the time for better vision and the code was installed under the helmet\'s flap - a dimmed led, not bright -, so the worker could see it all times. gepetto_father

Yes, as above, it is important to decide which information should be given to whom. Otherwise it may lead to unintentional panic. bahars

good idea, I could try any blink system with colours maybe, cause with the red light you don´t see very well durica

This is a really good idea, but as a badge with a warning on the jacket but effective. How can the tale as a work lamp use user not found
