In addition to bike headlights, what other equipment is necessary for night riding?

Wearing reflective clothing while riding at night is essential for ensuring visibility to other road users. When visibility is low, such as during night hours, reflective materials can significantly enhance a cyclist's presence on the road. These materials reflect light from car headlights, making the cyclist more noticeable and thus reducing the risk of accidents. This safety measure, combined with bike headlights, creates a better chance for drivers to see cyclists in time to react appropriately.

Other options, while beneficial in specific contexts, do not address the critical need for visibility at night as effectively as reflective clothing does. Sound horns and rearview mirrors can enhance safety but do not increase visibility in the same way. A GPS device, while useful for navigation, does not contribute to visibility at night.
