Buying Guide for the Best Rear Bike Lights Our Picks for the Best Rear Bike Lights Final Thoughts

Why buy a rear bike light?

As bikes move slower and have smaller silhouettes than cars, drivers often overlook cyclists out on the road. A rear bike light will increase the probability that you’re seen while on the road and help you avoid getting in an accident. The more visible you are, the better. The same holds true for trail or mountain biking at night. With a taillight, cyclists coming up behind you will also be able to react before there’s an accident.

What should you look for in a rear bike light?

What else should you know about rear bike lights?

Many people are surprised to know that 75% of cycling accidents happen in daylight. That’s a lot! Fortunately, you can improve your visibility easily by keeping your rear bike light on during the day. The higher the lumens, the better. Of course, riding safely at night is still critical. Most fatal bike accidents occur between 6 and 9 p.m., so be extra vigilant when riding during those hours.
