LED Safety Light (4 Pack) - Clip On Running Lights for Runner, Kids, Joggers, Bike, Dogs, Walking The Best Accessories for Your Reflective Gear, Nighttime, Bicycle Cycling

Lights are great. Bright, so I taped some electrical tape over the front to soften it for my preference. Surprised it came with four elastic band Velcro, handy for attaching or for other uses. Four mini screw drivers to change the battery is a nice touch. With flashing lights, it seems the batteries will last a long time. Been used for over 40 hours and still going strong. Would buy again.

The product is great for safety after dark and before dawn when I walk my dog. It fits securely on her collar and on my vest. It is visible for quite a distance.

For a simple blinker it is made very well. 3 blink modes that are plenty bright. I clip them onto my Granddaughters when they ride on any of their toys. Good price plus extra batteries!

Using these on a dog collar seemed more of an incidental use. These are clearly intended for bikes, backpacks and areas where it can clip on securely or use a provided velcro loop. If this were really intended for dog collars, it would include a metal or other sturdy loop to hang properly from the collar.The clips have proven durable enough to stay in position on the collar, over time, with a rambunctious puppy's movements.These are very bright lights, but have to say the provided batteries don't seem to last very long. I'll order a well regarded battery brand on my own and compare any difference, which I would expect to be an improvement in longevity.

I was skeptical as to the effective brightness of these little clip lights. However, I found these led lights to be very bright. The clips have “teeth” ridges and secure well. I placed them on my molle strap of my backpack and sling bag for extra visibility at night, especially on my motorcycle. The included velcro strap is very secure for options such as handle bar or similar attachments. They are too short for using as wrist band.

Bright and easy to use. Two flask modes or constant on. Has a velcro strap to mount to objects like a bike frame. I use them for early morning running in the dark. Just clip on my pockey or sleeve and cars can see me.

These are pretty good lights, but they should just stop including a tiny little screwdriver to remove the tiny little screws to replace the tiny batteries. I have resorted to just throwing the things away instead of replacing the battery, as I find it very difficult to get them open. It's just not worth the frustration and risk of jabbing myself. They really need to redesign these lights.But at least they're cheap.

These red flashers are bright!! They blink flash, or blink slower, or stays on fully bright. I used them on my daughters Halloween Costume for trick or treating so others could see her. I clipped two in her hair and two on her waist. They stayed on for the 4 hours of fun!
