Oops. Works on my sterns, didnt know ,met, imdn, kiss

Quoted from stoptap:

I think he said he tapped off the GI.

Quoted from stoptap:

That’s a bit of a bummer. So you can’t add another light for one of the controlled inserts ? Bit of a pain in the butt when it comes to homebrew mods.

Hey todd123, this is Ryan from Comet Pinball. Here is what I would suggest for what you're trying to accomplish (five different colored lights on each of the characters in your topper, illuminated at all times).
Get an alligator clip and connect it to the lugs of one of the GI sockets in the back of your game. Probably this would be one of the bulbs in the back corner. The lugs will be sticking out underneath the playfield. The lugs on each socket might have head shrink tubing on them...you can cut this away with a scissors to expose the metal and then clip on the alligator clips: https://www.cometpinball.com/products/standard-matrix-connectors?variant=12493661995052
This will give you a connection that supplies 5v...so to that you'd like to connect anything that is 5v or 6.3v (which will also be fine). You can connect multiple bulbs / strips to this and will be fine.
Then get a 36 inch wire: https://www.cometpinball.com/products/matrix-extension-wires?variant=12493662191660
Run this from the alligator clips up through the head of the machine, and up to the top (possibly out one of the air vents in the back).
Then get two three-way splitters: https://www.cometpinball.com/products/matrix-splitter-wires?variant=12493662388268
Connect one to the end of your 36 inch wire, and the other to one of the connections on the other one. You'll be left with 5 connections. One for each of your lights.
For lighting, strips are an option. We have different colors and different lengths (and you can easily cut them down to a shorter size if that's what you need). They will have a low profile so they could stick to the top of the cabinet. The downside is that you wouldn't be able to aim the light too specifically. But, maybe that's not necessary: https://www.cometpinball.com/products/lighting-strips
Another option is to use sockets (which we are currently out of but should have back in stock in the next week or two or three): https://www.cometpinball.com/products/add-on-light-sockets?variant=12493659635756
You can stick any bulb you want in there. Opmax would be a wide, diffused source (but bright). 1 Watt Magnums would be bright and very focused. Something like 4smd would be somewhere in between. You could even use a 1smd flex to be very very specific about how the light was directed.
The upside to sockets is that you could focus the light more specifically. The downside is that they don't have as low of a profile as strips, and you'd have to either drill into the top of the machine to affix them with screws (or find some way to tape them down that would stay) or you could mount them to something. It could make sense to have a foreground of some other material that would serve as a little wall and the lights could be set up on the other side of the wall to obscure how they're being lit from the player perspective.
Sorry, that was probably a lot...just wanted to give as full of an explanation as I could. Does that make sense? Let me know what other questions you have.
