keyboard LEDs
SirPeale:
Anyone know what the average voltage on a keyboard PCB for the LEDs is? I would guess 5v, and I'm sure I'm wrong.

It is 5v. I tested it a while back because I was bored and had a multimeter.

Then the existing LEDs on the PCB must have a resistor inline. Hmmmm....

Depends on the keyboard. I've seen them both ways...

If I have a 2-player cabinet, with one lit button for player 1, and one lit button for player 2, is there any use in installing the 3rd LED somewhere??

I'm actually thinking of putting mine in the marquee to light up certain parts brighter like the back glass of an pinball machine.
