How many red tail-lamps are required on each side of a trailer under 80" in width?

In Texas, for any trailer that is under 80 inches in width, it is required to have two red tail-lamps on each side. This requirement is set in place to ensure visibility and safety on the road, particularly for vehicles that may be behind the trailer. The dual lights provide a clearer indication of the trailer's presence and help prevent accidents, especially during low-light conditions. Having two red tail-lamps on each side maximizes visibility to drivers in various situations, enhancing safety and compliance with traffic regulations.
