I heard about it so I made one up
I took a magnetic LED rock Light
Sodered a 15 ft cord with Cigarette lighter attachment to it
So now I have a dunebuggy work light
Pretty cool
with the magnet it attaches to almost everywhere around the buggy
engine compartment ,front end, under the dash or the picnic table or tent so if I need a light
I now get a lot of light
yes a flashlight is plenty, I just thought this was pretty neat
