RottayBike Wheel Lights, Bicycle Wheel Lights Waterproof RGB Ultra Bright Spoke Lights 14-LED 30pcs Changes Patterns -Safety Cool Bike Tire Accessories Kids Adults-Visible from All Angle

I bought this light and one other for the back tire. Each came in a package of two so I shared with a friend. All the kids in the neighborhood are jealous and can't ride after dark because of safety concerns. We senior citizens like to circle the block, honk our horns and play old people music until curfew!! Roflmao too much fun !!! These are great!! Bright colors and easy to install according to my husband!

Really excited about this purchase. I was skeptical (low price, not a brand I knew...) and ordered a set to test. Arrived as expected: packaging was minimal, design was simple, battery was not included. Tested on my daughter's bike in the garage and was impressed. Very easy to install & use. Very bright. Very cool. Not sure how fast you have to go to see all of the shapes/patterns as shown, but for what I wanted this was excellent. All of my little nieces and nephews are getting a pair for Christmas.

For night riding -- and to some extent -- day riding, this gadget is fun for the children. They love seeing the patterns swirl around as we are biking, but this can also be dangerous: drivers (or your children) may get distracted and hit something. But importantly, it makes you very visible at night, keeping you hopefully a bit safer.Keep in mind that some places may find the use of these lights as illegal. Check your local laws.Requires 1 AAA battery (not included). Activates with motion and turns off after a few seconds of no movement. Patterns can be changed by the press of the button, and as you ride, the patterns also change.

Work great.To all the people who thinks that the lights not working when they insert the batteries and press the button, in the video shows that you press and hold the button and then they will turn ,not just push and let go ,have to hold for a bit but it’s working….watch the video on how to turn them on.

These lights are really fun, but you do have to have a decent stretch of road/path for the designs to appear. I bought them for my kids bikes while riding around a campground for safety/visibility. It's really dark at night, lots of pedestrians, golf carts, and vehicles to contend with. These unfortunately didn't give the effect I was hoping for for visibility. They are fun to look at if you can catch the kids going fast enough, looking enough, but not as much as light as I had hoped. I will keep them on the bikes for the fun factor, but will order additional lights to make them more visible for safety.

I had to return the first pair I bought because I thought they were broken. Mainly, because the instructions aren't very clear. You're supposed to hold the power button for 2 seconds to turn them on, just fyi. To get them to flash in synchronization you'd have to turn them on simultaneously. Not sure if they have settings to where you can have them flash a specific color because I ordered blue lights but received "rainbow"

The media could not be loaded. This item does not work when you screw the battery cap all the way on.I ordered the 2 pack so both by kids could have one on their bike. This one is smaller than some of the other wheel lights so I could use it on the smaller bike. I used new batteries and could not get either one to work after you screw the batter cap on all the way. When you initially put the battery in and start to put the cap on it will illuminate. Unfortunately once you start to put the cap all the way on they no longer work. I did see some users bend the metal coil and it worked that way, but I feel I should not have to modify the product to make it work. There are other reviews stating the exact same issue I had.

Received as expected. Love the colors. Item is sturdy and well made. Easy to attach. Easy to use.
