There are no good spots, you need a separate supply for that quantity of LEDs. Cointaker sells a nice 3A 12VDC supply for this purpose:

Lol @ power supply. A couple led strips are fine. J116-j118 all provide 12vdc. Here is a picture: http://pinballbulbs.com/installs/wpclighstrip11.jpg

They're all the same power source. It doesn't matter how you divide it. A couple strips are no biggie. Pinball bulbs kits come with 2-4 light strips and all plug in there.

I would suggest to just be certain that where you are tying into will handle the amount of current the LEDs require. Most LED strips draw more current than you might think. I would calculate the draw of the strips and the available current from your source before adding any mods. Better safe than sorry.

Under cabinet lighting takes a whole roll of the stuff. A couple feet of strip aren't compatible to that.

I agree.

I did not see in the OPs post anywhere where the strip length was mentioned just the words "a couple of strips", in my mind that could be a anything - is that a 1 foot strip? A 6 foot strip? A 20 foot strip?

I was just commenting for the benefit of the random reader to have some idea of the current draw of what they are installing beforehand. Carry on.

Listed to a markmon on this. I hooked 3 of my kits to 1 machine just to see what kind of problems may occur, no issues carry on. That was done on a Tz by the way.

That sounds like overkill to light what you are talking about but I could be wrong.

That is a power supply to plug into a controller as well btw so you would be spending $50 before even getting a strip there. If you do go controller method its to change colors and such, get it on amazon http://www.amazon.com/LEDwholesalers-Controller-2034RGB-3315-3215/dp/B0040FJ27S/ref=sr_1_1

Controllers suck, interactive is much better. Just my opinion.

It all depends on what look you are going for. I do like interactive myself and controllers have some really cool uses like a TZ backbox fading door or congo volcano mod.

I added an interactive flasher set on my Metallica and it is awesome. I like getting the teals and other colors in there when boatloads of flashers are going off

Check out www.dkpinball.com. I sell power taps for just this sort of thing.

Your power taps are awesome for these types of mods. It makes life easy for the user.
