Metal shields that are easily installed over the automobile lights during a blackout are offered by a Chicago inventor in shapes and sizes to fit most recent car models. The hoods are slotted to throw a beam of light visible 100 yards ahead, but visors and baffles prevent any light from shining upward or against the ground, where it would be reflected and become visible to an airplane observer. In a test made with the blackout shields on a city street, no light was visible from the 19th floor of a building. The set of hoods, available in a protective metal box, includes coverings for headlamps, tail lamp and the rear license light.
