What is required for a vehicle in terms of lights according to state law?

In Texas, state law stipulates that vehicles must be equipped with several essential lighting systems for safety and visibility. This includes having two headlights, tail lights, brake lights, and turn signals.

Headlights are crucial for nighttime driving and adverse weather conditions to ensure the vehicle can be seen by others and to illuminate the road ahead. Tail lights serve to signal the vehicle's position to vehicles behind, while brake lights are vital to indicate when a vehicle is slowing down or stopping. Turn signals are necessary for communicating lane changes or turns to other drivers, thereby helping to prevent accidents.

Without this comprehensive lighting setup, the vehicle would not meet safety standards, which could pose a risk to both the driver and other road users, particularly in low visibility conditions. Thus, the correct answer reflects the complete range of lighting requirements mandated by state law, highlighting the importance of maintaining these features for road safety.
