Turn Signal

A turn signal is a light that indicates the direction an automobile will be turning. These lights are located on the front and rear of vehicles. While usually the light is orange, there are turn signals that exist in the same light as tail lights. The turn signals blink intermittently. A turn signal can also be an arm out the window, when the lights are damaged or malfunctioning. An arm straight out means a left turn, and an arm bent at 90 degrees, pointing up, signals a right turn.
