Orbit Brightz

They are cute in the dark, easy to install. I have ridden on singletrack as well as smooth pavement and they've stayed in place. I will check back to report on battery life. There are two lights in a pack, they light up on one side. You can see the light from both side of the bike but I think more lights per wheel would look even better.

They work well on my kids’ bikes, but my kids have a hard time turning them on. They usually twist them too far and they end up completely coming apart. Easy to put the battery back in and working again, just a little annoying

These are great to help with limited visibility. both my kids have them on their bike and it just more light to help cars see us. They are not bright enough to light up the road and surrounding area. Easy to install onto the spokes and you just twist them to turn them on and off.

Still is working after almost a year on my daughter's bike that sits outside in the weather 90% of the time

Works well, bright, easy to install
