| OLD SYSTEM OF LIGHT PROJECTION DAZZLE POINTS Three features hitherto unavailable go to mark the advance of “TELEPHOTE” above all other lamps : 1. A ready focus device that can be adjusted by the driver in a few seconds to meet any type of weather when driving at night. 2. A light that is definitely anti-dazzle, giving a powerful spot of light with a minimum range of 300 yards under normal driving conditions — projected forward and eliminating dispersed illumination in the immediate front of the Vehicle, which is acknowledged to be the main cause of what is commonly known as “back glare.” “TELEPHOTE” can be kept at full intensity and requires no dipping or dimming when used under varying conditions. 3. A light that will pierce fog and give 50 to 70 feet of driving vision. AFTER a lengthy period of extensive research and exhaustive tests, we have the pleasure to offer to all road users a revelation in the projection of light, namely the “TELEPHOTE” Lamp, which has been proved the unquestionable solution to all Fog and Anti-Dazzle problems.
