No, you'll probably have to buy two separate LEDs to light up 2 rejects.

So with two LEDs, can I hook them up in parallel to the computer power supply?

I'm so useless with electricity, I am replying to my own posts...

I guess this would be a perfect solution to hooking up 2 of the LEDs:

Ken Layton:

You are perfectly fine to use either #194 or #161 dashboard lamps. Each lamp draws a quarter of an ampere so wiring two in parallel would be a draw of only a half an ampere from your power supply. Modern commercial arcade games use two #194 lamps to light up the coin entries and they are usually wired to the game's switching power supply.

LeedsFan:

I'm interested in this too.  I'm converting an existing Jamma cab and I've isolated the game board power supply. But it seems a shame to not utilise the light that's already in the loom for the coin door. I agree LEDs are better, but I may as well use what's already there.

How would I wire this into the 12V supply for a second hard drive? Do I just splice the red and black wires from the block connector? As per original poster, I'm not too hot on computer electrics.   ::)
