How many rear reflectors and what color must they be on a trailer?

Trailers are required to have two rear reflectors, and they must be red in color. This requirement is outlined in Texas vehicle safety regulations to ensure that trailers are visible to other drivers, especially in low-light conditions. The use of two red reflectors enhances visibility and safety, contributing to the overall compliance with traffic safety standards. Red is chosen specifically for the rear reflectors to convey a warning to other drivers that they are approaching the back of the vehicle, which is crucial for preventing accidents.
