OK...I was given this light as a gift:
Originally I had planned to mount it permanently to the rear roof of my FJ40, with wiring passed through the roof to an inside battery/power source.
So now I am thinking of a way NOT to have to punch a hole through the roof.
What about attaching the base of the light to a rare earth magnet, and placing one magnet inside and the magnet mounted light on the outside? A power cord would then run in through the rear vent window.
It should be fairly simple to take on & off when moving.
How about the mounting the light to the magnet? Epoxy? A small recessed screw or bolt?
Any drawbacks I haven't considered?
