What color should tail lamps be to meet Texas vehicle safety standards?

In Texas, the law requires that tail lamps, which are positioned on the rear of a vehicle, must emit a red light. This regulation is in place to ensure that vehicles are easily identifiable to drivers behind them, especially in low visibility conditions such as at night or in poor weather. The use of red for tail lamps is a standard adopted not only in Texas but also in many other states, allowing for consistency in vehicle lighting across different regions. This color signaling helps prevent accidents by clearly indicating a vehicle's presence and its intentions, such as stopping or turning, to following traffic.
