If you have ever been out on a bike ride after dark, you know how important it is to have some sort of light to illuminate your path. Even if you don’t make a habit of riding at night, you should still consider buying a bike light. You never know what can happen on the trail, and most bikers have run in to unexpected delays on more than one occasion. Say, for example, you planned a four hour trail ride that put you back at your car by dusk. What if you get injured and have to walk back? What if you need to make an emergency road repair that puts you behind schedule? My point is, you should always be prepared for all possible scenarios, and biking at night is dangerous without proper lighting.
