Moon Cerberus rear light review – it's not perfect, but this classic model is still very good

Versatile rear light with excellent 270 degree visibility and decent run times, but room for improvement with the mounting system

Cycling Weekly Verdict

If you are looking for a light to fit a variety of seat posts, the Cerberus might be worth considering. The versatile mounting system and 270º coverage sets it aside from many other lights, it’s no surprise it’s won design awards based on these aspects. It’s not perfect though; the hinged mounting wings could be better positioned to improve stability and the rubber pad could do with a permanent fixing to keep it attached to the light. These niggles aside, the light is certainly a slick unit that will get you seen day or night.

Moon’s Cerberus rear light has been around for a few years now. The innovative design was recognised when it launched in 2018 by Taipei Cycle d&i awards and again in 2019 by iF Design

It certainly enhances visibility on the road, but is it still a worthwhile investment fours years on, with so much more competition from the best bike lights on the market?
