Makes a average bike cool lokking.
My bike was just average-looking until I draped the frame with this colored LED rope light. Now, I get compliments like - "cool bike!". The AA batteries (not included) seem to last a long time. You have to be careful wrapping the rope around the frame and securing it. I damaged one set. To secure the frame, I used very small pieces of clear tape. The LEDs are very vivid. especially during night rides.

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

Easy to install
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.

UPDATE: I love(d) these lights
I love these lights. Yes, they are LED lights on a copper wire, but don't seem frail at all to me. In fact, the attachment for the battery pack was incredibly easy to install, then I just wrapped, wrapped, wrapped and next thing I knew I had adorable, colorful lights brightening my path in the gloomy streets of Portland, OR. I'm not only more visible with these, but they bring smiles to faces when I ride by. Love them! So far so good, after a month in the rain no problems at all. Will update if anything changes. UPDATE: One year later, the lights just died. They got dimmer and dimmer, then only one color would come one, then they died completely (not a battery issue). I think $20 is a little much to spend for lights that will only last a year. I did love them and would consider buying them again, but am bummed at their durability.

Excellent
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.

Great When it Works
It was great when it worked. I used this in conjunction with the wheel lights and it was great. Unfortunately, unlike the wheel lights; these lights do not have any casing whatsoever. They are just bare wire with LEDs on them and connected to a power supply/control console. They were great for a few months until one of the wires snapped, after that it only worked from the the power supply up to that point. I had my friend solder the wires back together, but a few weeks later a different area snapped. I am planning on using clear heat shrink wrap on it and see if that helps. I will update this if it does.

Great bike lights and bright
Great product! It's a tad shorter than the one bought years ago (maybe 4 or 5 yrs ago) Love that the lights change to a wide spectrum of colours, and can press the button again to lock on the colour. Love these as they have double the LEDs than other light strands, water resistant, bright and durable

Missing pieces
Lights work fine but rubber frame mounting strap was missing.
