My intention was to save some money and write thread about how to do it and where to get the stuff so others could do it. The main problem I had is finding a rheostat built to handle the amperage. I burned up a bunch of stuff trying to make various capacitors and rheostats work. There is just no other 12 volt application for it so they are not produced and offered in any quantity. I finally ended up using one built for RV interior fixtures. Even that one ended up being bad and I had to have them send a new one. I think even that source is dried up as it's a construction component and not offered as an aftermarket product sold in small quantity. Also IMO the current cheap gazillion power spots you buy at Walmart and Meijer do not have very good beam focus and don't seem to generate the type of illumination that the tufflights do. For that reason I don't use the one I built other than as a backup. Not saying it can't be done. Just not really worth it.

There was a thread on here with pictures but I can't seem find it.

Some scientists claim that hydrogen, because it is so plentiful, is the basic building block of the universe. I dispute that. I say there is more stupidity than hydrogen, and that is the basic building block of the universe.
