  • Bright, fairly easy to install
Color: Green
They are bright for their size, fairly easy to install, once you get them untangled. Was a little worried they would break but actually went on ok. Helps me grandson be seen at night.

  • Easy to install
Color: Multicolor
Our second set of these we bought to replace the older ones. These are on a lightweight wire you just wrap around the bike frame. Easy to install. And with a previous set we did find the battery box rubber strap breaks eventually but we just strapped it on with a small bungee after it broke. And if the wire breaks the lights before the break will still work (happened eventually on the previous set). Over time the battery box leaked so we eventually replaced with this new set (the bike sits outside a lot and lights lasted a year or two at least). Nice bright little lights to add visibility to the bike at night. ... show more

  • It lights up my power chair perfectly
Color: Color Changing/Color Select
I bought it because I could not find anything else to light up my power chair so I'm outside at night time people can actually see me and not almost hit me it is the perfect thing for my power chair and for my safety

  • Works well, durable enough for a parade
Color: Rainbow
I participated in a Christmas Parade with my Motorcycle. They wanted us to decorate the bikes. I got a couple of these and zip tied them to the case guards on my bike. My Wife did the same with her Spyder. We rode at freeway speeds for an hour to get to the parade. We then attended the event, rode home at freeway speeds, and not a single light failed. We are probably getting more next year. ... show more

  • Disappointed but works
Color: Red
I first saw this at Walmart so I bought it as an impulse and it was a good light at night. They only had one color at the store so I bought this one and it's a totally inferior design. This one is much more difficult to install because of the small screws you have to deal with to change batteries. This cases does NOT seam water-tight at all. The other one has a self closing mechanism that's much better and is lined with a rubber gasket. This one has nothing. This one uses velcro which sucks when wet and breaks down. The other one had a simple tight rubber strap closing that worked better and easier than dealing with 4 tiny screws. Same company for sure just different designs and it's hard to shop and see a difference because there are no model numbers either. Bottom line there is a better version available and this one IS NOT IT. ... show more
