Derek here are the photos you requested of the light. (I figured out how to post thumbnails that you can enlarge if you wish.)
JRk here is the stop lignt and mirror. The stop light is brand new and never installed. It just needs cleaned up (sorry, I don't have it in the mail yet)
Ok seems the cheapest thing to do is go kick start only and that opens up a bunch of options for cheap batteries. He is my battery box spotted in

Next I will need to weld in a plate for the electronics. They will go between the seat brackets.
This next step is going to cause lots of raised eyebrows. But I figured WTF, I'd give it a try. The bike can not be rode with the stock pegs. That was a give in. I have to be very frugal with everything I do so I started looking at the rear brake set up and came up with somethng that I think will stay. It is free and it seems to work just as well as stock (for me). I rotated the main brake shaft upside down (like this

) and cut and rewelded the brake lever (like this

) . The throw is much shorter but you are over top of it now and can easily put as much weight on it as you wish. In the stock position the lever was in a position in front of you and mostly you use your calf muscle to operate it. You did have the advantage of a long lever, and it was engineered back in 1975 to allow a 155# man to lock up the wheel. But now you sit over top of it and it is lined up under your leg, so you can operate it by pressing with your entire leg if you wish. JRK will understand this. It's like the difference of a seated calf press and a leg press. The throw is all of about 1.5" and I can lock up the back wheel by pushing down with my thumb. I can't push the bike around with my thumb on the brake lever. I realize the bike is not going 90mph but I think I can get more leverage with my leg than I can with my thumb, so I should be good to go (or stop, haha). I don't like the idea of bending linkage rods and not expect them to bend back straight under load. I'm a pretty big guy (215#). This way all the linkage is still is straight and there is no way I'd ever bend anything trying to ge the bike to stop.
It was very critical to get the angles correct. The brake lever is positioned so that as it rotates you you are pressing in a downward motion (the arc is very short so you don't notice its circular rotation) which allows you put weight on it if needed. I don't think it will get to that though. Besides in the end, Brakes just slow you down anyway. lol
I plan to change the foot rest to bmx stunt pedals and will be fabing a shift lever and doing up the linkage. In the end, if the rear brake doesn't live up to what I think it should do, I'll change it.
