I'm working on a puzzle (game) that I can't seem to figure out.

http://i204.photobucket.com/albums/bb268/gweedoh/image003.jpg

Both puzzles are on 12 volt electrical circuits with incandescent lights on the top puzzle and LED lights on the bottom puzzle.

The answer for the top puzzle should be something in the neighborhood of 33 and the answer to the bottom puzzle should be in the neighborhood of -112.

I have no information about what the numbers given represent. I've tried a few calculations solving for watts, amps and ohms and I can't seem to come anywhere near the expected results.

I'm thinking there is something in the way they are configured that makes this more of a simple add-em-up type of solution.

Any help or hints would be greatly appreciated!
