Multiple-beam road lighting equipment
Sec. 20. Except as otherwise provided in this chapter, the head
lamps, the auxiliary driving lamp, the auxiliary passing lamp, or a
combination of these lamps on motor vehicles, other than
motorcycles or motor-driven cycles, must be arranged so that the
driver may select between distributions of light projected to different
elevations. The lamps may, in addition, be arranged so that the
selection can be made automatically, subject to the following
limitations:
(1) There must be an uppermost distribution of light, or
composite beam, aimed and of an intensity to reveal persons
and vehicles at a distance of at least three hundred fifty (350)
feet ahead for all conditions of loading.
(2) There must be a lowermost distribution of light, or
composite beam, aimed and of an intensity to reveal persons
and vehicles at a distance of at least one hundred (100) feet
ahead. On a straight level road, under any condition of loading,
none of the high-intensity part of the beam may be directed to
strike the eyes of an approaching driver.
(3) A new motor vehicle, other than a motorcycle or
motor-driven cycle, registered in Indiana after January 1, 1956,
that has multiple-beam road lighting equipment must be
equipped with a beam indicator that must be lighted whenever
the uppermost distribution of light from the head lamps is in
use. The beam indicator must not otherwise be lighted. The
beam indicator must be designed and located so that when
lighted the indicator is readily visible without glare to the driver
of the vehicle so equipped.
As added by P.L.2-1991, SEC.7.
