i took a cheapo cig lighter socket usb car charger to pieces, it has a little PCB inside with a chip and a few capacitors to regulate the voltage. I desoldered the usb plug (but you could do it with a usb extension plug) , desoldered the wires to the led & extended the wires, added an inline 3amp blade fuse holder and a switch, and took the dremel to a switch blank as you can see! Then epoxy everything into a solid block in the back of the switch blank. Power from the original cig lighter via a vampire clamp and earth to a bolt by the handbrake.
took about an hour and a half probably, be quicker next time!

stu -
switch turns usb power on and off, since the usb car charger already had a built-in voltage regulator its the proper 5v usb.
i did take a few more pics but they\'re not that helpful, i will dig them out.
