Brightz CosmicBrightz LED Bike Frame Rope Light - 6.5-Foot String Rope - Battery-Powered with On/Off Switch - Ultra Bright Color Keeps Your Ride Fun and Safe for Kids, Teens, & Adults

Love, love, love these lights. They are super easy to install, and the colors (I chose rainbow) are so pretty! They show up wonderfully in the dark, and I feel like such a "cool kid" when I'm riding in my neighborhood at night. The batteries are easy to change out as well. The only thing I wish they included is more than one plastic tie-down. On the eve of my 14th birthday, a brake cable came off my handlebars and dropped into my spokes, while I was going down a hill. I flew over the bike and broke my arm*, so I am a little paranoid about things coming off my bike. *after coming home from the hospital, my parents let me open one of my birthday gifts early. It was Billy Joel's album The Stranger. (I'm super old). At least I had Billy Joel to comfort me as I sat there in pain with my cast on. I still love that album, although I the don't care for rest of his music! (Sorry to any BillyJ fans).

Why did you pick this product vs others?: Used them to personalize my daughter's wheelchair. Very easy to use and they look great. Very bright

Very cool bike lights! They are bright and very durable. Water proof. My son rides his bike through the woods and leaves it laying around everywhere. These lights havent broken or fallen off yet. I will definitely buy these again.

Love the brightness and ease of usage, works well to customize on different lights and the batteries are easily interchangeable.

This is the second one that I've bought. I put it on my son's bike and he loves it. It works well to make him visible to drivers when we ride in the evenings our at night, but to him it makes him feel like his bike is super cool. My son's drum instructor saw them and said he wanted to get some to wrap around his bass guitar. I imagine they could be used on all kinds of things. They were easy to install both times. The battery pack lasts a long time. As a matter of fact, the first one he had for over a year and never changed the batteries. The only thing that kept me from giving it a 5th star was why we ended up buying the second one top begin with. The first one broke after leaning the bike against the edge of the truck bed during transport. The wire that the LEDs are strung along is very thin. This is a tough one though because if it were any thicker, it would be more difficult to install and generally less pliable. Although, had it been thicker, it would have severed the wire so easily. That's why this issue didn't affect my decision on the repurchase. I would recommend this product.

Cool on bikes

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.

Purchased a different set of bike lights (same brand) in 2023 and they’re still working great, no issues. This pink set that I purchased December 2026 is defective. Part of the strap for the battery pack broke within one month. Then the whole product broke within two months.
