On the diorama.
Been sniffing around after an arc-flash simulator for quite a while, but they're stupid expensive for what amounts to about 50 cents worth of LEDs.
Found this one on Amazon for about $9 so figured I'd try it out. Stupid simple, 2 white LEDs and one blue LED flashing at different rates. Comes pre-wired all you have to do is connect power to it and via some magic I don't quite under stand, anything from 9 to 19 volts AC or DC will work. I had my doubts but it works very well.
