Sec. 547.333.  MULTIPLE-BEAM LIGHTING EQUIPMENT REQUIRED.  (a)  Unless provided otherwise, a headlamp, auxiliary driving lamp, auxiliary passing lamp, or combination of those lamps mounted on a motor vehicle, other than a motorcycle or moped:
(1)  shall be arranged so that the operator can select at will between distributions of light projected at different elevations; and
(2)  may be arranged so that the operator can select the distribution automatically.
(b)  A lamp identified by Subsection (a) shall produce:
(1)  an uppermost distribution of light or composite beam that is aimed and emits light sufficient to reveal a person or vehicle at a distance of at least 450 feet ahead during all conditions of loading;  and
(2)  a lowermost distribution of light or composite beam that:
(A)  is aimed and emits light sufficient to reveal a person or vehicle at a distance of at least 150 feet ahead;  and
(B)  is aimed so that no part of the high-intensity portion of the beam on a vehicle that is operated on a straight, level road under any condition of loading projects into the eyes of an approaching vehicle operator.
(c)  A person who operates a vehicle on a roadway or shoulder shall select a distribution of light or composite beam that is aimed and emits light sufficient to reveal a person or vehicle at a safe distance ahead of the vehicle, except that:
(1)  an operator approaching an oncoming vehicle within 500 feet shall select:
(A)  the lowermost distribution of light or composite beam, regardless of road contour or condition of loading;  or
(B)  a distribution aimed so that no part of the high-intensity portion of the lamp projects into the eyes of an approaching vehicle operator;  and
(2)  an operator approaching a vehicle from the rear within 300 feet may not select the uppermost distribution of light.
(d)  A motor vehicle of a model year of 1948 or later, other than a motorcycle or moped, that has multiple-beam lighting equipment shall be equipped with a beam indicator that is:
(1)  designed and located so that the lighted indicator is visible without glare to the vehicle operator; and
(2)  lighted only when the uppermost distribution of light is in use.
