NEW DEVICE FOR HEADLIGHT

Motorist With Can of Paint Should Be Able to Fix Lights to Suit Laws of Any State. The Illinois law requiring the dimming of headlights on approaching an-’ other vehicle does little more than make a formality of what has long been a custom. More drastic laws in other states, however, bid fair to get the Chicago motorist into trouble If he tours far afield without-due preparation. ; ■ ■ ' Many headlight devices have been approved for use In these states, but the simplest suggestion for comply-, ing with the most of the varying regulations seems to be that suggested by Macey F. Deming, who framed the law now in. effect in New York. Mr. Deming says five minutes spent in painting your light bulbs will give a motorist an effective nonglare device tn anystate.FOr New York he describes the method as ■ follows: YPaint the right side of the light bulbs green and at the tip of each bulb make a circle of green paint onehalf the diameter of the bulb. The paint should cover the right of the bulbs, looking with the car, for an arc of 150 degrees.” Painting the right side of the bulbs is prescribed because the New York law limits the apiount of light that many be directed-to the left of the car. The reason for this is the fact (which some motorists know and many don’t) that the light rays which come from

the right side of a bulb strike the reflector and aire thrown to the left-hand side of the road—and, of course, vice versa, as indicated in the diagram. Keeping this In mind, and remembering that to limit the light thrown upward one must paint the lower side of the bulbs, the motorist with a can of paint should be able to adapt his headlights to almost any state law.
