Its late right now but I will have to dig it out and look at it... don't know how to post pictures.

I used the automotive bulbs that go into car tail lights. they have 2 posts on the bottom. Each one I believe was approx 2amps for discharge purposes.

Lie them flat alternating directions of the glass part... one up... next one down... next one up... make sure that the poles on the bottom of the bulb are aligned so you are able to wrap a wire around it.

When you solder it... solder the sides of the metal together... this will be black if I recall it correctly.

Now... take the red wire and cut a section that will be soldered over the poles of the light, then wrap it around and you will have to cut the rubber coating off in order to solder it to the next one. When you get through you will have a corkscrew effect. Solder a black wire to the side of the bulb at the end you will be hooking to your battery. Hope you left enough wire on the red side on the poles to attach your battery connector or alligator clips.

If this sounds strange, sorry, it's the only way I know to describe it. But you must watch your voltage to make sure you do not go below the minimum voltage of your cells.

If you can figure out the amp draw on the motor and setup you are using, you can build the lights to match the discharge rate and see how much you have left if you feel like trying to up your gearing.

This light was built about 15 years ago when 1400SCR cells were the "in" thing.

Figure out how I can post a pic and I will take one of my light for you to see.

Hope this helps.
