What lighting is required at night on animal-drawn vehicles?

The appropriate lighting requirements at night for animal-drawn vehicles include having one white lamp at the front that is visible from at least 1,000 feet and two red lights at the rear also visible from 1,000 feet. This lighting setup is crucial for ensuring visibility and safety on the road, allowing other drivers to see the vehicle from a safe distance during nighttime conditions. The white lamp at the front helps illuminate the path ahead while also signaling to oncoming traffic, while the red lights at the rear indicate that the vehicle is present and moving in the opposite direction.

In contrast, the other options do not meet the safety standards required for night visibility. Two green lights visible for 500 feet would not provide adequate warning or visibility to other drivers, particularly because green typically signifies a go signal in traffic contexts. A red triangle on the rear, while helpful in some contexts, does not provide sufficient visibility to indicate the vehicle's presence at night. Finally, amber lights on both sides are not standardized for animal-drawn vehicles in the same way as the specified white and red lighting, which is specifically designed to enhance safety for both the operator of the vehicle and other road users.
