Designed with a rechargeable Lithium-Ion battery, this rear light can last up to 19 hours on a full charge – enough for around two weeks of daily commuting. Additionally, this light also comes with a battery indicator, so you can keep a keen eye on how much charge you have left. With a water-resistant alloy casing, this light remains impervious to poor weather conditions and heavy-handed bike riders alike. Thanks to the universal quick release bracket and silicone strap, this light should fit around all seat post shapes and can be transferred between bikes in seconds.

Excellent Rear Light

Very bright rear light. Comes with multiple fittings. 2 seat post fittings one saddle fitting and one clip fitting. Fast USB charging. Light seems to last a long time between charges. Just bought a second one and would buy again. Very impressed.

Comet x-pro failed after 3 months

Seems well made, worked well for 3 months but now won’t turn on, just flashes once only and stops despite pressing power button as instructed.

Bright compact but not reliable

I bought this for my 40km round trip commutes on an eFat bike and used it in the cold Canadian winter months too. It is nice and bright, compact, mounts well, and has long run time on a charge. However, I always found it tricky to turn on and then after a year it died. One day I could only get it to work while charging. I noticed moisture inside and dried it out at very low heat in an oven but that didn’t revive it. I don’t consider a year a long enough life for a light at this cost. In my mind the quality is questionable and it can’t be fully waterproof.


Nice light. Lots of options for mounting so that is a bonus. Good battery life and easy to charge. Best part is it is easy to mount, use and see. Lots of different flash patterns to help you stand out and very bright even in full sun.

Moon Comet X Pro

Great light, just what I have been looking for especially with the saddle clamp allowing the neat and tidy installation of the light tucked in under the saddle


Works as advertised. Straps to seat post efficiently
