Sec. 489(50). Additional permissible lights on vehicles.
(a) Spot Lights.—Any motor vehicle may be equipped with
not to exceed two spot lights, except that a motorcycle shall not
be equipped with more than one spot light, and every spot light
shall be so aimed and used, upon approaching another vehicle,
that no part of the beam will be directed to the left of the center
of the highway, not more than one hundred feet ahead of the
vehicle.
(c) Other Exterior Lights Prohibited.—No vehicle shall be
with two side lamps upon the front of such vehicle and projecting
a light to the front or side and conforming to regulations adopted
by the commissioner. No electrical lamps or bulbs exceeding
four standard candle power shall be used in any such side lamp.
(c) Other exterior Lights Prohibited.—No vehicle shall be
equipped with any lighting device other than those required or
permitted in this or the preceding subsection except that this provision
shall not be deemed to prevent the use upon a motor vehicle
of interior lights of low candle power, nor the use of vacant
or destination signs on vehicles operated as public carriers.
(d) Auxiliary Lamps.—Any motor vehicle may be equipped
with such auxiliary lights of low candle power and illuminated
signal devices as may be permitted or required under this section
or the rules and regulations adopted by the commissioner.
(e) All vehicles with bodies extending over the wheels on the
sides and measuring seven feet or more in height from the ground
shall, in addition to the lights hereinbefore required, carry two
white lights on the front of the body, and two red lights on the
rear of the body so placed as to plainly show the width and height
of such vehicle, both front and back.
