Or have you noticed flickering lights or lightning streaks that you knew weren't really there? We also scoured the internet to discover some of the most popular rear bike lights when it comes to reliability, safety, and ease of use. In addition to following our own advice, we read what other critics and riders had to say about their favorite taillights on various message boards, social media platforms, and publications.

A light that produces 15 lumens can be seen at night but may be tough to see during the daytime. Generally speaking, the higher the number of lumens, the brighter a light. Lumens are a unit of measurement that describes how visible a light will be. Here’s what to know when finding a taillight that’s right for you.
