er lenses may be contrary to the new
law In his demonstration, Mr.. PIN
placed the charts at a distance of %
feet from the headlights. showing
by focusing the light upon its chart
ed surface how the lenses must be
regulated. a loose bulb. the speak
er declared, would tend 10 interrupt
the proper focus and this was prov
ed. He also showed that a mere
diffusing lens is not legal because
no focusing OF the headlight bulb
will throw the rays from such a
lens below the danger line. He also
demonstrated that the Ford green
painted lens, as well as other painted
lenses. are not legal because they
do not throw the kind of light re-
quired by the law.
