At night, how far must a bicycle's front white light be visible?

The correct requirement for a bicycle's front white light to be visible at night is indeed 500 feet. This regulation is designed to enhance the safety of cyclists by ensuring that they are visible to motorists and other road users from a significant distance. A front light that can be seen from 500 feet allows drivers to notice a cyclist well in advance, giving them sufficient time to react and provide the necessary space while passing.

Visibility is crucial during nighttime riding, as it significantly increases the chances of being seen, reducing the risk of accidents. This distance is established to create a standard that all cyclists must adhere to, ensuring that they are not only legally compliant but also prioritizing their safety on the road. Having a reliable light that meets this visibility requirement ensures that cyclists are responsible and considerate participants in traffic.
