Handy Portable Light Cost Just $30
For about $30 you can build a 6-ft. high portable service light that can be used anywhere because it operates off the battery of any vehicle, says inventor Kirk Harrold.
A pair of lamps mount on top of the stand and can be rotated in any direction. The lamps mount on a detachable bracket that you can lift off, if needed, to get a closer look at some-thing.
The stand was made with a 6-ft. length of 1/2-in. dia. water pipe that's threaded on both ends with a T-joint at the bottom.
To make the lamp mounting bracket you weld a 10-in. long, 1-in. wide flat iron - with a hole drilled into each end - to a pipe joining collar that screws into the top of the stand. A 1 1/2-in. wide piece of angle iron with a hole drilled into it is then welded onto the center of the flat iron. Then the bracket-supporting collar is screwed onto the stand. Harrold mounted a toggle switch in the angle iron and connected both leads from the lamps to one of the switch terminals. He attached a fuse to the cord's power lead (black) and then to the remaining terminal on the toggle switch.
Attach alligator clips to the free end of the cord and wind the cord onto the cord bracket. The clips can be attached to the battery terminals of any 12-volt vehicle.
