Show Beacons for Motorists. The flashing beacon used on the high seas by the leading nations of the world is now to be used as a highway high-way guide for motorists. Like the beacon at sea, tha city traffic traf-fic Is an unwatched light, automatic in operation for months at a time. Fuel Is supplied by an acetylene gas accumulator accu-mulator In the base. To these beacons and highway lighthouses light-houses is applied the national system of colors approved by the committee of standards of the American Association Asso-ciation of State Highway Officials, and by other national organizations and many cities in the United States. Red Is used for first degree danger, yellow yel-low for second degree, and green for traffic danger only. Two hundred cities are reported to have standardized on this national color signaling, which Is that of the railroad systems, and almost as many have made Installation of the flashing flash-ing light traffic beacon as an effective warning for drivers who are partially, or wholly, color blind, and those who find it hard to distinguish the ordinary signal from other city lights. The flashing beacon is the invention of Dr. Gustav Dalen, winner of the Nobel prize in physics In 1912. From The Motor. |
