Dazzle Screen. While in London yesterday, I saw at Kents, Holborn, what appeared to me to be a very simple but efficient screen to combat the difficulty of driving in the face of dazzling lights. It consists of 2 oblong auxiliary screens of blue glass, each about 5" x 3 1/2", attached to the ordinary windscreen in such a position that the driver at ordinary times could see between the screens, or when approaching dazzling head lights, by moving the head one inch sideways, could protect his eyes from the approaching head lights. Possibly you may already be aware of this appliance, but, if not, I would suggest that you try a pair. Wd.{Mr Wood/Mr Whitehead} | ||
