(b) A motor vehicle may be equipped and when required under this chapter must be equipped with lamps or mechanical signal devices showing to the front and rear for the purpose of indicating an intention to turn either to the right or left.

When actuated the lamps must indicate the intended direction of turning by flashing the lights showing to the front and rear on the side toward which the turn is made. If mechanical signal devices are used for this purpose, the devices must be self-illuminated when in use at the times required by IC 9-21-7-2. (c) A stop lamp or signal lamp or device may not project a glaring light. (d) A lighting device mounted on the rear of the vehicle may not display any color other than red except as follows: (1) A signal lamp or device must be red or amber or any shade of color between red and amber.
