21466.5
. No person shall place or maintain or display, upon or in
view of any highway, any light of any color of such brilliance as to
impair the vision of drivers upon the highway. A light source shall
be considered vision impairing when its brilliance exceeds the values
listed below.
The brightness reading of an objectionable light source shall be
measured with a 1 1/2-degree photoelectric brightness meter placed at
the driver's point of view. The maximum measured brightness of the
light source within 10 degrees from the driver's normal line of sight
shall not be more than 1,000 times the minimum measured brightness
in the driver's field of view, except that when the minimum measured
brightness in the field of view is 10 foot-lamberts or less, the
measured brightness of the light source in foot-lambert shall not
exceed 500 plus 100 times the angle, in degrees, between the driver's
line of sight and the light source.
The provisions of this section shall not apply to railroads as
defined in Section 229 of the Public Utilities Code.
