vehicle may be equipped and when a signal lamp or device
is required under this Article shall be equipped, with a signal
lamp or signal device which is so constructed and located on
the vehicle as to give a signal of intention to stop which shall
be red or amber in color and signals of intention to turn to
the right or left, all of which signals shall be plainly visible
and understandable in normal sunlight and at night from a
distance of 100 feet to the front and rear but shall not project
a glaring or dazzling light. Stop signals need be visible only
from the rear except in the case of School Busses provided for

be so arranged that the driver may select at will between dis-
tributions of light projected to different elevations, subject to
the following requirements and limitations:

(a) There shall be an uppermost distribution of light, or
composite beam, so aimed and of such intensity as to reveal
persons and vehicles at a distance of at least 300 feet ahead
for all conditions of loading. The maximum intensity of this
uppermost distribution of light or composite beam 1 degree of
arc or more above the horizontal level of the lamps when the
vehicle is not loaded shall not exceed 8, 000 apparent candle
power, and at no other point of the distribution of light or
composite beam shall there be an intensity of more than 75, 000
apparent candlepower.

(b) There shall be a lowermost distribution of light, or
composite beam, so aimed that:

1. When the vehicle is not loaded, none of the high inten-
sity portion of the light which is directed to the left of the
prolongation of the extreme left side of the vehicle shall, at a
distance of 25 feet ahead, project higher than a level of 10
inches below the level of the center of the lamp from which it
comes.

2. When the vehicle is not loaded, none of the high inten-
sity portion of the light which is directed to the right of the
prolongation of the extreme left side of the vehicle shall, at a
distance of 25 feet ahead, project higher than a level of 5
inches below the level of the center of the lamp from which
it comes.
