Benefits of Using Bike Lights
It may seem obvious but there is a dual benefit in cyclists using bike lights in dim/dark conditions. They are used to not only to increase the rider’s visibility, but also to help others to see the rider. Lights are an extremely important piece of equipment as statistics suggest a car-bike collision rate is several times higher at night than during daylight. What is more startling is that these collisions are largely down to the inadequacy of the cyclist’s equipment which can be easily prevented. Using the proper equipment makes cyclists visible to other road users and can make cycling at night much safer than this statistic suggests. The most common setup for bike lights are white lights at the front of the bike, red lights at the back, and orange reflectors on the side, but be sure to check the legal requirements of your jurisdiction as there are different rules on what is required.
Looking specifically at the UK, the regulations governing bicycle lights are set out in the Road Vehicles Lighting Regulations 1989
