Brightz CruzinBrightz Disco Party LED Bike Light, Tri-Colored - Blinking Swirling Color Patterns - Bicycle Light for Riding at Night - Mounts to Handlebar or Bike Frame - Fun Bike Accessories

The kids loved these on their bikes. Makes for fun night riding.

The media could not be loaded. I wanted some lights for my stroller for Halloween trick or treat and for the holidays. These are great and look like a party. They are meant for a bike but fit wonderfully on the side of my joolz aer+ stroller.The only thing I didn't like is it comes with a screw but not a nut, which makes it easy to fall off. I went to Lowe's hardware store and found the screw fits a M4-.70 nut and wingnut. There's a groove that can fit the nut, so what my husband plans on doing is superglueing the nut to that part of the light (pictured) so the nut stays on and makes sure the bolt doesn't fall off, and we add a wingnut for additional security.

The media could not be loaded. Just purchased two of these for use at Burning Man this year. I popped the 3XAA batteries in at home and even with some evening ambient light outside, there is a very clearly visible pattern on the ground. :)I think if someone was wanting to use these as a 'headlight' for their bike, they would be barking up the wrong tree. The pattern changes configuration several times a second, and does not provide a nice spotlight for forward vision. That being said, by placing this on the front of the bike, it projects an image down on the ground to make the moving bike unmistakenly visible, which is my goal in the middle of the pitch dark desert. The idea is to not be struck by other vehicles, people and bicycles. I just hope that the light will not distract the rider's focus ahead. Ha. Also, I don't think that my actual headlight will cancel out the pattern of the decorative lights as they are illuminating different areas.I'm going to have to adjust placement with the basket present on the front of the bike covering the handlebars.The clamp to attach to the bike appears to be a nice textured rubber, for good grip. If it slips, will duct tape it on, or use plastic zip ties.I also like the fact that the lighting unit unsnaps from the clamp to prevent theft, or to just have fun with in general.The light is bright enough that I didn't want to look at it directly. Angling it up toward the ceiling if off the bike, or down on the ground on or off the bike would be the way to go.In all, very satisfied with the purchase.I feel that bike riders can't do enough (alright, maybe they can) to be visible to others at night. Would very much consider this on my default bicycle at home if I'm out past dark.If depending on this for visibility and not for fun, i would keep an extra set of 3 AA batteries around. I can't vouch for battery life yet.

This is definitely fun for biking at night, especially during festival season, but it’s definitely one of those very cheap novelty items (prob cost less than 1$ to make), not sure how long it will last. On line the on/off button only turns it on not off (if I unscrew the battery case, it will turn off and when I re-screw the batteries back in it doesn’t automatically come on so I can press the power button then. Not the worst thing since it’s probably not a bad idea to take the batteries out when not using, but it’s definitely obnoxious. I’m honestly not sure if this is by design or a flaw bc there were only instructions on mounting (kind of) nothing about operating.

Our Cycling group did a Christmas ride, at night. Everyone had their bikes lit up. Some people live up their wheels. Others lit up their frames. I chose this and it was a lot of fun. FYI, it only works if it’s really dark outside

The light is actually great. The mount wears out quickly however. If you don't do any curb jumping or off-road, maybe only smooth path, I'm sure this will last a lot longer.

The media could not be loaded. Brightness is good, FYI the clamp isn’t super adjustable and the close part isn’t a hinge like many bike light mounts. Won’t accommodate wider than a standard seat post. Lights are great though!

Great product great service great fabulous job all around and more so!!!!
