Brilliant light

Really bright rear light with loads of attachments.

Be Safe. Be Seen

Have always used Moon lights. This model was purchased as my son and I are heading out earlier in the mornings. Great rear light. In the dark it is seriously visible from distance. Good variety of options depending on bunch vs solo riding [ was told too bright for someone following when they focused on the light 🤟] Easy to install & saddle option as well. Only negative is different USB connector vs other models so need separate cables however not significant enough to sway buying decision. Highly Recommended

Nice light

Got this for 6 months now. And i am impressed that it is bright. Highly recomended


Fits securely to the back of my seat post. Really bright I will be ordering another for my other road bike.

"The Best!"

I bought both the front and rear Moon Nebula lights. Without question, the best lights I have bought over the last 20 years. Well designed, good looking and high quality materials. I can recommend this product without hesitation.

Moon Nebula rear light

Bought this light at the best price I could find anywhere and It also included delivery. I chose this one because it came with a saddle mount which is what I wanted as having a dropper post meant it was the best fitting option. The light itself is well made and has plenty of different lighting options, some of which may be even too bright to use on road and would upset a few motorists. Can't comment as yet on the battery but it came with at least half a charge and it didn't take long to fully charge it. All in all at this stage I'm more than happy with the light and also with Probikekit and I will definitely be keeping an eye on their website for any other possible purchases I may need.


I would 100% recommend this rear light. I had the older version and that finally give up the ghost so I got a newer one and it has more light modes to select from the best is rear on with a puls flash every other second. you won't be disappointed.

Moon Nebular Rear Light

Excellent light day or night, comes with many options to attach to the bike or helmet with adjustable angles, very happy with this light, I have one for my helmet and one for the bike. Very good battery life on day flash. Be safe be seen. I am going to fit one on my electric scooter.

Good performance, but not in wet weather

Rear light is large and provides plenty of light. Very powerful at night. Only problem experience is in heavy wet weather, water ingress occurs. Water resistance is only for light drizzly rain. Not good enough for heavy rain. Amazingly, light started working again once dried out with a hair dryer.

Moon Nebula Rear Light

Very bright, great for day and night use.
