Jennifer nelly: Not worth buying. The picture shows the light lighting the whole wheel while moving. Well when we put on car and bike it did not show anything like the picture... wouldn't recommend showed up in mail cheap plastic and batterys all dead.

NoVa: My 14yr old son wanted these for his bike, I'm so glad I bought them! The instructions suck but its still worth the buy. 1 of the 3 batteries in 1 of the lights leaked acid a little and didnt work but I changed that 1 battery and the light works fine. You get quite a few lights so 4 are going on my car as well lol

Ashley Goodfellow: Some of the lights were broken and didn’t work and the ones that worked I put on my car and they didn’t last long few days and died and I also had a set on my bike and same issue as my car the lights didn’t work that great and broke easy. Made of cheap plastic I would not recommend this

Mandy McGee: I love these. I put them on my bike and they work great. Their not very noticeable during the day, though you can still see them. However they look amazing at dusk/night.

Michael R.: Folks, you get what you pay for. This is not some insanely good deal you've run across. Mine came badly packaged,all lose in a bag. Several were broken off. I had one set of the same color not broken, but one of those doesn't work at all. As far as I've seen, they are junk. Live and learn

KWheel: As others have said, there were a few DOA. One had the batteries installed upside down and worked when I corrected that problem.

The solid colors light while the wheel spins. The multicolor sequence flashers go through their entire sequence once triggerd by motion and will continue to do so as long as the motion continues. Once motion ceases they will finish the current sequence then go out.

I did put one on my road bike so I could ride the neighborhood with the kids and be cool too. However, as others have poined out the presta adapters let the presta valve stem push the batteries up off the contact. I left mine loose but that could not be a permanent solution to use these on presta. There are, and I have, more practical lights on my road bike anyway.

So, expect a few dead ones but with 10 in the pack (my pack arrived with 12) a few bad ones still makes this a bargain.

kidd3791: I really wanted to like these. I use them at the campground on our golf carts so the driving isn't extreme. Within a few days the clear caps were coming off. They actually screw in. I had to unscrew and glue them back in. The chrome lowers are plastic. They do stick out pretty far so keep that in mind. Must have kicked them about 4 times in the first weekend. That being said, most of them work very sporadically. Some are dimmer then others (batteries old, faulty connection?) and some don't turn on while driving. You can't beat the price but you are getting what you pay for. Wish they sold just the multicolor sets as everyone seems to love those.

Honest T.Honest T.: My second order of these bike lights arrived today by Cosmos. They came in a different package ( bag ) than my first order. I have had bad experiences using the Fire Fly lights in the packs from China. So I hope these are better since they do have the Presta connector, unlike the ones from China. I know all these are from China regardless, but it is a different set of lights. If you have Presta valves you need to be very careful in screwing in the Presta adaptor. And you need to install the adaptor by itself without the light assembly. Be super careful when you install the Presta adaptor and when you feel a slight resistance, you stop turning! Pull on the adaptor to make sure it is threaded in correctly. I ruined 3 Presta connectors because I over tightened these adaptors too much. They stripped and the valve would come off easily. Realizing what I had done. I was very careful installing the adaptors. Once I made sure they were securely on, I installed the light assembly. I screwed in the light assembly and I did the same thing. Once I felt resistance, I gently screwed in the light just a slight bit more and stopped! The light was on and it didn't fall off or...
