Years ago I was at a KC Hilites booth somewhere and the rep gave me one of their universal tube clamps, designed to mount driving lamps or other things to a roll bar or cage. I tossed it in a drawer and forgot about it—until recently, when I bought a rechargeable Streamlight Stinger flashlight to be dedicated to the FJ40. 

Since the tube clamp is plastic it was easy to drill it to mount the flashlight’s charger base to it with stainless 3/16th bolts and nylock nuts. I mounted the assembly to the roll cage above the passenger seat, where it is out of the way but accessible to either passenger or driver. I ran the power cord down the vertical tube of the cage to the 12V socket I installed in the dash there a few years ago (above a DIN socket).

The KC tube clamps are available in various sizes, to fit tubes from .75 to three inches. The possibilities for uses are endless.
