“Fascinating indicator tower ideal for those "rising panic" situations :-)
Lights barely glow at 8.5v, usable at 9v, stable brightness from 12v to at least 24v.
Main description is wrong about multiple lights at the same time - you can light any or all of them - they are independent of each other - draws 80mA at 12v with all LEDs lit and 20mA for the sounder (can't hear the sounder as I'm deaf).
Now to build my death machine mwahahaha :-)”
