Flashlight Enthusiast
One of the early electrical novelties powered by a battery was a simple stick pin with a miniature bulb. Wires connected the bulb to a battery hidden in a pocket or behind a scarf (tie). When the wearer pressed a switch carried in the pocket, the bulb flashed. "D" batteries powered the scarf pins. The scarf pin was a novelty when introduced, but users discovered practical uses for it, such as reading in dark restaurants or theaters.

Isn't that exactly what some of us EDC for? And another thought, a *D* cell EDC, and people complain about 2 x lithium 123 today..... /ubbthreads/images/graemlins/grin.gif
Though I'm wondering how long a D cell could drive a 5mm LED for. Energizer's datasheets say something like 18000 mAH for the D cell, characterized at 25mA - perfect for a small 5mm. Let's see, 720 HOURS.. or thirty days nonstop.
American Electrical Novelty and Manufacturing Co. of New York was formed to sell these new battery powered devices.Misell and Hubert assembled a number of tubular flashlights and gave them to New York City policemen in different precincts. As shown in the first catalog, by March, 1898, Hubert began receiving favorable testimonials from the policemen. Testimonials are statements from people extolling the virtues of a certain product. These testimonials were used in the company's literature to promote sales. Hubert was a great salesman and the publicity obtained by the testimonials made the public want to own a flashlight.
The brand name of the products was "Ever Ready". During the first few years, the name "Ever Ready" did not appear on the light. By about 1902 the name was on the light.
Let me rewrite that.. substitute American Electrical with Laser Products, "Ever Ready" with "Sure Fire"... /ubbthreads/images/graemlins/smile.gif
Fascinating webpage. Almost makes me wonder if I can slap a Hotlips in some of those old 2Ds with a BB917 and drive a regulated 5W Luxeon off 'em. The shock power of such a mod is going to be incredible /ubbthreads/images/graemlins/crackup.gif
