From the time my son was about 10 he always loved wires. Getting through his bedroom without getting tangled in them was always a problem and I never knew what new idea I might be pulling apart. By the time he was pre teen he had aquired several hazard lights from a construction company and had wired them to his stereo so the lights danced to the music.
In the Navy he worked on helicopter wires and now works on the harnesses for the tow missile, tanks & torpedo's. He also developed an LED headlight for the Lancaster, Pa. Amish community buggies.
This son holds a patent on an LED light. It took lots of money and many hours, in fact years,but he finally did get the patent. Now he is taking it one step beyond just a light. A local Fireman has been testing his "pimped up mag light" in the dark & smoke. They came up with a way to mount it that it is free from the visor. This is always exciting to see something new being developed. I'm waiting for him to develope a light for my sewing machine, soon maybe.
