How many tail lights should a moped have and what color?

A moped is required to have one tail light, and it must be red in color. The red color is standard for tail lights on most vehicles, including mopeds, as it serves to warn other drivers of the vehicle's presence and indicate when it is braking. The requirement for one tail light is consistent with safety regulations, as it ensures visibility from the rear without overcomplicating the design of the vehicle.

Other color options such as blue and yellow are not standard for tail lights. Blue lights are generally used for emergency vehicles, while yellow is typically reserved for turn signals or hazard lights. Having two tail lights, while sometimes seen in design variations, does not align with the specific regulations for mopeds, which clearly state the need for only one tail light. This helps streamline the regulatory framework for mopeds, ensuring clarity and ease in compliance.
