What is the legal requirement for turn signal lights on motorcycles built after 1973?

Motorcycles built after 1973 are legally required to have turn signal lights that are amber in color. Amber signals are used because they provide a clear and universally recognized indication of a turn or lane change intention for other drivers and road users. This requirement helps enhance visibility and communication among vehicles on the road, promoting safety for both motorcyclists and other motorists.

While some older motorcycles may have different requirements, the use of amber for turn signals in newer models ensures consistency and adherence to safety regulations. The other options do not align with the legal standards set for motorcycle equipment, emphasizing the importance of color and functionality in signaling.
