About: Mars Light

An Entity of Type: lighthouse, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Mars Lights are signal-safety lights used in the United States and built by Mars Signal Light Company for railroad locomotives and firefighting apparatus. Mars Lights used a variety of means to cause the light to oscillate vertically, horizontally, or both, to catch the attention of motorists and pedestrians. Mars lights were developed by Jerry Kennelly, a Chicago firefighter who realized that oscillating lamps would benefit fire departments and railroads. He performed an operational test with the C&NW railroad in 1936, and Mars Lights began appearing on locomotives in the later 1930s.

  • Mars Lights are signal-safety lights used in the United States and built by Mars Signal Light Company for railroad locomotives and firefighting apparatus. Mars Lights used a variety of means to cause the light to oscillate vertically, horizontally, or both, to catch the attention of motorists and pedestrians. Mars lights were developed by Jerry Kennelly, a Chicago firefighter who realized that oscillating lamps would benefit fire departments and railroads. He performed an operational test with the C&NW railroad in 1936, and Mars Lights began appearing on locomotives in the later 1930s. Tri Lite, Inc. announced their acquisition of the Mars Signal Light Company, effective January 23, 1991. Tri Lite still manufactures many of the traditional Mars Lights under the Tri Lite Mars brand. The company has updated the Mars "888" Traffic Breaker with energy-efficient light-emitting diodes replacing the earlier halogen incandescent bulbs. (en)
  • マーズライト(英語: Mars Light)は、アメリカ合衆国の鉄道や、消防車のためにが制作した安全信号灯群のことをいう。赤色とは限らない。 会社名が形式の総称として残っており、おもに8の字の特徴的な扇形の往復回転運動形式を言う。バリエーションが多々有り、往復する間に何度かの角上下動を組み合わせた8の字型に光線をゆらす形式が有名。しかし近年では左右1組装着されたライトで交互の点滅する( 英語: Ditch Lights)もマーズライトと混同し呼ぶ事も増えている。安全信号灯ファンの中でも一ジャンルとして残っている。 実際の動きはサザンパシフィック鉄道GS-4形蒸気機関車等で見る事ができる。 (ja)
