Activ Life LED Bike Wheel Lights with Batteries Included, Get 100% Brighter and Visible from All Angles for Ultimate Safety & Style (1 Tire Pack, Galactic)

In the order of how often I'd use them, whether the lights were easy to install, the quality of the lights, how long the battery lasted, and other comments I had on them:I would use these on my bike every 2 weeks or so on night-time rides on campus and would ride around for anywhere between 2 to 5 hours long.The lights were sometimes a pain to install, but then again, I would install them in the dark surrounded by the other bikes in close proximity; if you aren't cramped like I was when installing the lights, it would be far easier to install the lights. On the occasions that I did not install them cramped having to worry about hitting other bikes, the process would take me about 3-7 minutes, otherwise it would take about 10-15 minutes. It's just setting up the plastic rubber bands on the center of your bike (axle? I only cared about brakes and whether my tires had air), looping the thin wire down to be near the edge of the rims, and looping the wire up and down over each of the metal tire line things. See the end for additional comments.The lights themselves were bright and did not diminish in intensity during the 8 months or so that I used them. They were easily noticeable and helped in being seen when walking my bike through intersections at night. They were also bright and a nice green, nearly as bright as advertised (the advertisement has them to show as blinding X^D).I do not remember if they came with batteries but surprisingly, I don't think I ever had to swap out the batteries during the time I used them. As I mentioned before, I used these lights for about 8 months for anywhere between 2-5 hours every two weeks or so.Finally, my final opinion on these lights are that they are great and that I would buy them again. One thing to note is that you should not install them when stressed or tug on the wires hard as that is how I broke one of two that I purchased. The light still works and I am sure I can add something to prevent any accidents, but do be aware that the wires are a bit fragile. They are not cheaply made though, but should still be treated with some care. I hope this helped some of you, have a good one.

These are so much fun and they look great at night. We get so many compliments every time we go for a spin. Installation is easy. Cannot say I’ve had a single issue with them.

The only lights I can actually attach to my bike, leave there, and not come back to find them stolen. Theft-proof for real. Plus it looks cool, people love it and shout out compliments when I ride by at night. I don't need to turn them on often, but so far I haven't had to replace the batteries. I might have to soon, but I've had them for a while, so I'd say it lasts pretty long before you have to even worry about replacing the batteries, which are AAA so that won't be too hard. I got these cuz it's a pain taking off bike lights whenever I park, and if I don't they get stolen fast. These lights make me visible at night, look cool, and don't get stolen. It's cheap and totally worth it.

Fast shipping, good quality, battery life is solid and lasts for a long while. I bought these to fit on my aunt's wheelchair to add some fun to her daily life - get tons of compliments. We added double sided sticky tape to the back in order to adhere to the wheels. They are water resistant as we have been in and out of the rain multiple times. The brightness is good - I wish they were a little more on the deeper purple side but still love them. the fit is great as they were able to go around the wheelchair perfectly.

We saw these lights on a bicycle in our neighborhood and I knew we had to get some for our kids. For the parents, it is nice because you can see the bicycle from far away and it gives a sense of safety for twilight and nighttime riding. For the kids, it gives them something to enjoy seeing the lights as they ride. The lights are very easy to install and the instructions are easy to understand. The hardest part of installing the lights is installing the rubber "band" around the hub. It is possible with one person but a lot easier with am extra set of hands and the 4 step instructions that come with the lights let you know that.The lights have 2 operating modes. When you hit the button once, the lights flash about once a second. When you hit the button a second time the lighter stay on without flashing. The lights are REALLY BRIGHT and fun to look at. I thought it would be nice for trick or treating during Halloween.There is a positive and a couple negatives, but the POSITIVE FAR EXCEEDS the minor negatives.Negative #1: We ordered 6 sets of lights. (2 Blue, 2 Red, 2 Green) (The 2 blue sets are not here yet so I can only offer feedback on red and green for now) The first green set would not turn on when we hit the button. After a little troubleshooting, I noticed the screw cap that holds the battery pack in was not quite seating the battery pack in place. NOT A BIG DEAL. All I needed to do was put a little ball of paper in the end cap and screw it on. PROBLEM SOLVED.NEGATIVE #2: The second set of red lights we ordered seemed to test fine. We put the batteries in and turned it on. While still wrapped up in the packaging ball, all the lights looked like they were working. When I got about halfway done installing them, I noticed one of the lines was ripped. I hit the power button and noticed only half the lights were working. I decided to try to repair the wire but it was so thin that it was impossible for me with my limited amount of tools so I just cut the line at that point and tied it off on the wheel. I was going to leave it that way but decided to reach out to the company to see if they would swap it out which leads to the POSITIVE.OUTSTANDING CUSTOMER SERVICE!!! In a world of pushing phone buttons to talk to a robot that leads you to someone that many times can't help you with your issue, I can assure you that is not going to happen with these guys. I called the 1-800 number on their website and got an out of office recording. I left a message and we within 5 hours a member of their staff sent me a text message and an email with instructions on how to get a replacement. Keep in mind, I told them that it was working but only half. I offered to send it back for a swap but they told me to hang on to it and they sent me a promotion code for a new one through Amazon. I received the promotion code got the new one on order.I HIGHLY RECOMMEND this product for adults and kids alike. It adds a big safety factor to night riding and they are fun to watch.

We added these to my daughter's bike so she is easier to see when it gets dark earlier. Great purchase. Easy to install. She loves them.
