A colorless, highly flammable, and explosive gas that is commonly used for welding and cutting metal. In the early automotive days, it was used to fuel outboard lamps, and it's still used today as an illuminant.
A halogen, from the Greek words Halo ( "salt") and Gen ("creator"), is any of the 5 chemical elements in Group 17 of the periodic table of the elements. These elements are fluorine, chlorine, bromine, iodine, and astatine. Iodine and bromine gas are commonly used inside halogen light bulbs to extend the life of the lamp.
HID is short for High-Intensity Discharge lighting, which uses electrical arcs to create powerful illumination without drawing a lot of energy. Because of their energy efficiency and high power output, HID lighting is widely used for large, open spaces, such as stadiums, warehouses and roadways. More recently, HID technology has been developed for automotive lighting.
The kinetoscope is the progenitor of today's modern movie projectors. Edison, inspired by Eadweard Muybridge's failed Zoopraxiscope, sought to build "an instrument which does for the Eye what the Phonograph has done for the Ear." It was basically a device that simulated motion by moving a continuous loop of standard 35mm film over a light source with a rapid shutter. The spectator would look inside the kinetoscope through a magnified porthole, and he or she would experience the illusion of live action through the motion of the film. A later model, the kinetophone, tried to link sound and motion, but film breaks and poorly trained operators kept this technology from gaining popularity.
OEM is an abbreviation of Original Equipment Manufacturer. When a part is built OEM, it means that it meets the exact specifications of the auto manufacturer. In other words, the part is an exact replacement of the stock equipment.
