Moon Sport Cerberus Bike Taillight Review - feat. 150 Lumen + 3 COB LED Design + Round/Aero Posts

Named after the three-headed dog from Greek mythology, the Moon Sport Cerberus is a unique three COB LED bike taillight design. The multi-element Cerberus taillight retails for $46.99 and in this latest iteration has a 150 maximum lumen output. Power comes from an integrated 500mAh Li-Po battery that can be recharged in 2 hours with a modern USB Type-C charging port. There are also five different output modes to choose from, two steady modes and three flash options to cover daytime or nighttime riding. As with other Moon Sport products, the Cerberus output modes can also be fully customized with a Variable Lumen System (VLS) which allows the output of each mode to be adjusted independently. The other clever design feature of the Cerberus is the hinged mounting posts that allow the taillight to be mounted on round or aero seatposts without changing out any parts.

The Cerberus uses an industry standard rubber o-ring style mount that offers a quick and tool-free mounting or removal from the bike. With the taillight weighing only 36 grams, the rubber o-ring is more than enough to hold it securely in place. What’s clever about the Cerberus is the hinged plastic mounts on the base of the taillight instead of being molded directly on. This allows the Cerberus to be mounted on round as well as aero seatposts without any modifications or additional parts. The hinges also lie nearly flat which means the taillight can even be mounted on a flat rack or other locations as long as you can wrap the o-ring around. Moon Sport also includes two different sized o-rings to accommodate different diameter seatposts right out of the box.
Moon Sport Cerberus Taillight - Mount

With a three COB LED design, the Moon Sport Cerberus has a unique design that stands out on the bike. A center COB LED strip runs down the center of the taillight to provide rear visibility while two side COB LED stripes allow for improved side visibility. When illuminated, the COB LED strips provide a uniform glow that looks modern. The two side COB strips also have a Nike-like swoosh that follows the contour of the taillight. With its rectangular profile, the Cerberus sits flush and hides behind seatposts for an integrated appearance. Branding on the light is limited to a Moon Sport logo on one side and “Cerberus“ in a white modern font on the other side.

Wonderful detailed review. If only I could find reviews like this for every other product I'm considering buying!

Nice timing of this review. Looking to replace my twilight.

It has USB cable but only the Cerberus plug fits the light. I have a ton of cables in my desk drawer for things like Wahoo Roam and they all use the same plug type. So don’t lose the charging cable. 😅

Please have a look at the Moon Sirius Pro

Thank you for covering the Type-C aspect of it.
Does it charge with a Macbook USB-C charger? That is, does is support C2C cables or C2A only?

2 Cerberus in less than 3 years, really great design and also really nice light until... decided to not charge. Shop replaced on the warranty and now the second light is the same. Complain why MOON, but any answer back. Probably I will choose other brand. Thanks

I can't understand why this isn't a wedge shape in the opposite direction. It's deeper at the top which tilts it down on a post. Considering the post it already tilted in that same direction, having it deeper at the bottom would level the surface of the light perpendicular with level ground.. For a nice light like this, it seems like a strange design decision.

It’s ok with Mountain bikes it’s comfortable…and battery backup ? Pls let me know either Magic shine 180 ?

[LencoTB]

Where are they made? In which country?

[YUTfan]

Which of the two has better day time Day time visibility, Moon Sport Cerberus or Magicshine Seeme 200?
