| (a) Other than a sign permitted as an electronic sign,
a sign may not contain or be illuminated by flashing, intermittent,
or moving lights, including any type of screen using animated or scrolling
displays.
(b) A conforming sign may be illuminated but only by:
(1) upward lighting of no more than 4 luminaires per
direction of the sign face or faces of the structure; or
(2) downward lighting of no more than 4 luminaires
per direction of the sign face or faces of the structure.
(c) Lights that are a part of or illuminate a sign:
(1) must be shielded, directed, and positioned to prevent
beams or rays of light from being directed at any portion of the traveled
ways of a regulated highway;
(2) may not be of such intensity or brilliance as to
cause vision impairment of a driver of any motor vehicle on a regulated
highway or otherwise interfere with the driver's operation of a motor
vehicle; and
(3) may not obscure or interfere with the effectiveness
of an official traffic sign, device, or signal.
(d) A temporary protrusion may not be illuminated by
flashing or moving lights or enhanced by reflective material that
creates the illusion of flashing or moving lights.
(e) Reflective paint or reflective disks may be used
on a sign face only if the paint or disks do not:
(1) create the illusion of flashing or moving lights;
or
(2) cause an undue distraction to the traveling public.
(f) A neon light may be used on a sign face only if:
(1) the light does not flash;
(2) the light does not cause an undue distraction to
the traveling public; and
(3) the permit for the sign specifies that the sign
is an illuminated sign.
(g) This subchapter does not prohibit a temporary protrusion
area of the sign face that displays only numerical characters and
that satisfies this subsection and the requirements of §21.182
of this subchapter (relating to Commercial Sign Face Size and Positioning).
An electronic sign may contain a temporary protrusion described by
this subsection. The display on the temporary protrusion may be a
digital or other electronic display, but if so:
(1) it must consist of a stationary image;
(2) it may not change more frequently than four times
in any 24 hour period; and
(3) the process of any change of display must be completed
within two minutes.
(h) If the department finds that an electronic sign
causes glare or otherwise impairs the vision of the driver of a motor
vehicle or otherwise interferes with the operation of a motor vehicle,
the owner of the sign, within 12 hours of a request by the department,
shall reduce the intensity of the sign to a level acceptable to the
department.
