Just a quick question, I have 3 22mm lights in the panel I'm building. One is 220v for main power indicator and the other 2 are 110v for designating which emement is on. They are all LED lights. They don't have any markings on them as to which wire goes where. I know in dc applications LEDs will only light if power + - is hooked up right. In AC current does it matter which of the 2 connectors on the light is hot or neutral? And for the 220 light I'm guessing it gets 2 hot wires and no neutral? Thanks
