A correspondent of ” Motor Sport” writes

A problem associated with road transport which has received, a great deal of attention from inventors in recent years is the elimination of headlight glare, and the number of anti-dazzle devices now on the market are many and varied. Frankly, some of these are far from satisfactory, but others are very effective and certainly go far in making night driving more comfortable and safer for road users generally. In the latter category must be placed a device recently demonstrated to me which besides having definite qualities in diminishing glare, is also useful in foggy weather.

Briefly it comprises fine segments or vanes of ambertinted mica, pinned at their apex to a spindle, the whole assembly being fixed to the lamp glass. Attached to this spindle is a coil spring, which, when the device is in the “off” position, holds the vanes, packed one over the other. When the spindle is rotated (the action being transmitted from a small hand lever on the steering wheel through a Bowden wire), the vanes are spread out and shroud the upper rays passing through the lamp lens. A further rotation of the spindle extends the vanes still further so that the entire area of the lamp lens is covered, transmitting a yellow hue to the beams for driving in fog.

Practical tests under varying conditions have proved the device to be thoroughly satisfactory ; an advantage not found in a number of other anti-dazzle attachments is that it may be fitted to any type of lamp quickly and easily, the only operation required being the drilling of one hole through the centre of the lamp glass.

The inventor who has recently patented the device, informs me that he is anxious to market it and would be glad to hear from anyone interested in his project.
