Has anyone decided to make these kits and sell?
To sell, no, but I made one for my 70 and for an 80. I plan to make one for a friend's 40 and a 62 as well in exchange for some work.
At least for now I don't plan on making any others. You can make them using the diagrams @slcfj62 posted and the thread on Tacoma World. If you have any questions I am glad to help answer.
I know some prefer LEDs but I am in camp halogen. I don't like the radio frequency interference, appearance, expense, or snow/ice performance of LEDs. I also like that I can centralize my auxiliary circuits in one waterproof box.
