if installed, shall include four turn signal lamps, two single-faced
or two double-faced front lamps, and two single-faced rear
lamps. The two lamps at each end shall be mounted at least nine
inches apart and as far apart as practicable, with the front lamps
at least four inches from the nearest luminous edge of the low

attainable in one mile is 30 mph or less, are required to be
equipped with turn signal systems with the front turn signal
lamps spaced at least 16 inches apart and the rear turn signal
lamps spaced at least 9 inches apart. The lamp shall be so

also include a flasher and a visual indicator to the driver that the
turn signal lamps are on. The rear sections of double-faced front
lamps may serve as the required indicators. The lamps shall
project white or amber light to the front and red or amber light to
the rear. The lamps shall be plainly visible from 300 feet to front
