DAWAY LED Bike Wheel Lights - A12 Waterproof Cool Bicycle Tire Light, Safety Spoke Lights for Kids Boys Girls Men Women, 30 Fun Bright Patterns, Auto & Manual Dual Switch, with Battery

I found these really easy to fit on a mountain bike and they light up well and it's easy to choose different patterns and colors. My nephews had a lot of fun with them at Burning Man and they didn't fall off the bike despite going on what they said was quite rough, dusty terrain. Even though there was desert dust on the lights they continued to work.

This product is superior to others I have tested because the "Upgraded" version has a cable between the two lights. This is the only way you can truly sync 2 lights on one wheel. It looks much better with 2 lights on 1 wheel than only 1 light.

The product works as expected and is of a neat design. As others have documented the results are not as spectacular for kids and casual riders. When my granddaughter and I ride we average about 8 miles per hour. During that time the pattern only covers about a quarter of the wheel. If she gears up and really pushes on her 26 inch bike she can cover about half of the wheel. So to fill the full wheel I am sure that most riders are going to need to move pretty fast.Again this isn't really a design flaw, it comes down to wheel size, and how the eye/brain perceive the leds in motion. I am sure a 20 inch when turning more RPMs will show better results.It is a good safety tool to improve visibility and adds the "cool" factor for kids and adults. We also have powerful LED headlights and LED strobe taillights but these improve our side view profile.

The lights are sturdy and pretty bright compared to other bike lights. They are much more sturdy than others I have purchased. Only problem was one arrived broken so it only works part of the time. It looks like in shipping it got smashed, so I had to force the battery in the device. It still works most of the time, so I didn’t want to make a trip to UPS to get a replacement. I would recommend especially if you have a kiddo that falls a lot on their bike and is rough with their bike, they are the best light I have found that do not break or lose parts.

I have standard bicycle wheels and the lights were difficult to install, as stated in other reviews.Had to find the just right combination of spokes to install on. The treads for the nuts are not well made and can be easily stripped. I used lock-tite to keep them in place.The upgraded version comes with two modules connected with a wire, one set for the front wheel and another set for the rear.Are not as bright as I was expecting, but are bright enough for my desired intent, more visible to other people (increased safety at night).

I've had these for a few months now. At first glance, they worked fine. But after a few uses, I realized a few things that make them not worth the almost $20 price tag:1. I believe my pair came from two different sets. I believe this because on one of them, I have to hold the power button down for a few moments to turn on. On this one, once I turn it on, no matter how long I wait or make sure it's not moving, the lights don't turn off (showing it has turned off until the motion detector is activated). This kills the battery in a few hours so I have to hold down the power button to turn the lights off each time. And a few minutes ago I replaced the battery and now it will not turn off at all, even when I hold down the power button. I have to completely remove the battery to turn it off. So I considered this one broken.2. The second one works how it should. I lightly press the on button, the lights come on, then in a few moments, they go off. Once the wheel starts spinning, the motion sensor activates the lights and boom, perfectly working product.I will probably return these (if I can) in the hopes of getting another set that works. Otherwise I'm just gonna trash these and buy some other cool lights.These are definitely not worth $18. Maybe like $5-$10.

The packaging is easy to get into, and they even included an extra screw. It comes with a battery and is easy to figure out. The problem is that when attached to the wheel spoke there is not enough thread left on the other side for the cap to catch. I ended up using my drill to make the split go all the way to the cap. 1st photo what they sent on the right, and after drilling on the left. 2nd photo I used a screwdriver as a stand in for the spoke to show how little thread is left after attaching the device.I haven't riden it yet, so can't comment on the light functionality. But assume that if I don't update the review it works fine.Edit: I just figured out that you are supposed to put the screws through the 'wings' of the doohicky BEFORE putting it on the spoke. So, uh, yeah, I'm an idiot!

With it being a brutal summer, I wanted to get my long weekend bike rides started sooner before the sun came up so I could be inside before the brutal TX heat really kicked in.However, that meant heading out in the dark. While the area I ride in is generally respectful of cyclists, that's a moot point if they can't see you. I have the typical rear taillight for general riding. But I wanted more since it would be pitch black.An Amazon search turned these up. I took a chance and have used them almost 10 times, for close to 800 miles. So far they've worked great. They definitely light up the wheels. They aren't super bright, but bright enough for any car to see me at night. If I was riding in the day with these, they aren't bright enough and get washed out by the sun. So they don't provide any additional safety once the sun is up. But that's OK, too.Installation is easy enough, and the batteries have lasted thus far. Overall I'm highly satisfied. It gives me more confidence when riding in the dark. I feel lit up like a Christmas Tree with these and other lights I've installed. If I get run over by a car, it won't be because I wasn't seen. Highly recommended.
