A NEW diffusion screen, which is
claimed to be optically perfected, is being marketed by Trico-Folberth, Ltd., Great West Road, 13rentford, London, to replace the ordinary type, where it is considered that the illumination provided by the latter is not quite sufficient. At the same time, it comes well within the limits required by the lighting restrictions.
Almost clear instead of a milky edit
sistency, the latest. screen controls the strength of the light and the rays are scientifically distributed. On test, we immediately found a decided improvement, the illumination being particularly good straight ahead and at the extreme sides, so enabling cyclists and pedestrians to be seen more clearly and at a greater distance. This bright diffusion screen, number M154, is retailed at Is. 6d. and is easy to fit.
