9 Pack Led Safety Light, Safety Light, High Visibility Strobe Running Lights Used for Bicycle, Walking Etc. Clip-On Running Lights Clip to Clothes Strap to Wrist, Bike Or Anywhere(Red/Blue/Green)

Just got these today. They're very bright. I used the straps to fasten them to my sons stroller/bike trailer. I also put one on his wrist, the small velcro strap is perfect size for that (he's almost 2). The strap is way too small to fit an adult wrist though, but would work if you attach 2 straps together. All in all I'm very happy with this purchase to keep my son visible and safe on our walks/bike rides. I don't plan on removing them repeatedly, so hopefully they last longer than others reviews.

Very bright lights. I haven't had them long enough to speak about battery life.

I love these running lights since I often run at nights, because cars and bikers usually see me well, that is until the batteries run down. The newer 5 bulb versions are brighter than the 3 bulb ones, but then the batteries deplete faster. And while they are difficult to replace their batteries, they are cheap enough to just buy as disposables. They also come with optional Velcro strips so you can attach them to fingers, belts, straps, or dog collars, though I just clip them to my shorts or jogging pants, which works just fine, and they have never fallen off. Except for the batteries, I highly recommend them.

Bright lights with adjustable flashing or constant on. Great for walking the dog or nigh-time walking. I secured a couple of these to my snowblower so drivers can see me when clearing my driveway at night. You can see the lights flashing 50 yds away. You can even put them on tour car dashboard for emergency roadside stops at night. I will be ordering more. Great safety lights .

Works as described. I like how they come with the tools to open them up to replace the batteries and each one comes with its own velcro.

This is my second purchase of these lights, from separate vendors. The differences between the two models are subtle, and don't affect usability. The lights are much brighter than you might expect. If you look directly at them in the dark, they'll kill your night vision. There are three "on" modes: sequential strobing, which gives an up/down or right/left effect, flashing, where all the LEDS are lit or out at once, and steady on. I haven't conducted any battery life studies, but I assume that the batteries will last much longer with one of the strobe/flash modes. I've had only one light exhaust its batteries. Each light takes two CR2032 coin cell batteries. The battery compartment is accessible by removing four VERY small screws with an included screwdriver. The screws come out easily enough, but you need dexterity and, ideally, small hands to get them back in place. Pay attention to the configuration of the batteries, i.e. which side goes up in the place for each battery. One slot has the positive side up, and the other has the positive side down. I use these to clip onto my dog's harness when we take nighttime walks. I know the lights are bright, because I've had cars half a mile away hit their high beam headlights to see what the flashy light thing ahead of them was. Another use I could see would be to mark the location of a mailbox or driveway on a dark road when you're expecting visitors who don't know where the house is. Someone might come along and steal the light, but the lights aren't expensive, and you have a box of nine.

These lights come with strong clips, velcro straps, batteries (yeah sorry you can't charge these) and a tiny screwdriver for when you need to change the batteries. These use one of those coin batteries which in my experience last a long time. The great thing about these lights is how visible they are wether just on or in one of the blinking modes. These show up really well from a distance. I've gotten complements from bike riders on our local bike path for wearing these. They want to know what's coming up as much as I want to be seen. The combination of the built in clip and the included velcro strap make these very adaptable to attach to a wide variety of items. I wear a small over the shoulder pack when I walk. I was able to clip the green lights to the straps on the front of my body. And I used the velcro strips to securely attach the red lights to the part of the pack on my back. I'm really impressed with these nicely designed very functional-for me-safty lights. Great product and I'm really glad I got them.

Live and work in the south and run/bike before the sun comes up. Perfect for activity in the dark, running, walking bicycling, and helping to ensure you are seen by others. Alerts others in enough time to avoid collisions. Multipack is a cost saver vs buying individually or at a sporting goods store.
