ABSTRACT:
The headlight latern system comprises laterns with a rectangular pane having a height of less than 60 mm and a flattened concave reflector, in which a filament is arranged in a narrow tubular envelope. The filament has a very high color temperature and is surrounded by gas of very high pressure. The system produces a light beam which is superior to the beam of conventional headlight lanterns of considerably larger dimensions.
