161 bulbs
paigeoliver:
Now, the other zillion dollar question?
Arcade and PC power supplies are both largely scewed towards 5 volt output. Will adding 10 12 volt bulbs be "too much" for a power supply already powering a PC or gameboard?
I NEED to power these in some way. They are for my Stepmania panel. I special ordered those rectangle light up buttons that allow you to put your own graphics inside!

194 automotive bulbs are 12 volt and fit in the same slot. That's what I'm using on my coin door. They're wired in series and powered off the 12 volt lead on my power supply.

Sure you don't mean parallel? 2-194 bulbs wired in series would receive 6 volts each and be pretty dim for a 12 volt bulb...
Stingray:
Duh, yeah that's what I meant. I always get those terms crossed up.

Scottzilla:
Incandescent light bulbs usually don't care whether you put AC or DC through them (as long as you don't give them too much voltage).
161 bulbs draw .19A @ 14v, so they must be 2.66 watts. 10 of them would be 26.6 watts. If you run them at 12v (all in parallel) then they will be drawing about 2.22 amps. Check the 12v output current rating of your power supply and that should give you a clue as to how much room you have to play with.
