The Gray Light Car was a cyclecar built in Longmont, Colorado, in 1920 by H A Gray. Only two prototypes were made and, though articles of incorporation for the Gray Light Car Corporation were filed in July, it never reached production. Company officers were given as Gray, H M Koutz, G E Gumston, E J Kiel, and J H Vickery. Koutz and Keil were cigar manufacturers. Gray claimed to have advance orders for 2,500 cars. He did set up an experimental testing station at the McFarlane-Eggers Machinery Company on the corner of 28th and Blake Street, Denver.
