The Automobile Association has recently installed a number of A.A. superroadside telephona boxes which, in addiden to affording the usual telephonic facilities for motor-vehicle users, provide a welcome innovation in illuminated sigeposts. Erected at important cross-roads, they are larger and higher than the ordinary A.A. box now so familiar to road users. A steel post, approximately 20 ft. high. passes through the centre of the box and it car rice the necessary arms giving signpost information. The arms of the signpost are illuminated after dark by lamps using either low-pressure carbide, or, if available, electric current. The method of illumination coupled with the boldlettering, enables road information to be read after dark at a considerable distance.
