Everything about this is just perfect as a little gift for your puppy friends. Impressed a tiny tiny screwdriver comes to remove the four screws in the back for battery replacement someday. Even a velcro strap to optionally compliment the clip built onto the light. The spring loaded clip has a small pin that needs to be checked for security. I had one try to pull out accidentally. No big problem

We use these to deter Great Horned Owl predation at our Purple Martin colony. Owls were clinging to the entrances of houses and gourds at night with one talon and reaching in to grab both adult and baby birds with the other. Some other deterrents didn’t work out. Read that some others deterred owls with flashing lights and decided to try. It worked! We fledged quite a few baby Martins after losing too many to an owl. Oh, they’re bright, survived being used every night in rain and hail and wind. Ought to be great on bicycles, joggers and such.

These lights work well I work out in traffic and use them on my jacket.

I love these lights but the batteries are difficult to replace. Hard to unscrew.

I buy many of the lights of this identical style, operation and function. This package is among the better buys. I tend to exercise outdoors predawn and, even as sun is coming up, no form of reflective clothing or vests makes you reliably visible to others on the path, or bicycles or car drivers. I have nearly run into many joggers I can't see until the last minute, though when I have these lights, they see me. Reflective clothing requires the vehicles to have lights on and point at you, and the roads must be without curves. As sun comes up, drivers are blinded even more and people are going in and out of shadows. I have bought many of the available variations of this product, placing them on my shorts and shirt facing every angle. When I see lightless friends or neighbors or even strangers walking without light, I have taken a spare or two from a pocket and placed it on them. These are so inexpensive, and so are replacement batteries if you go that route. And batteries last a surprising long time. The one thing I dislike with many of the products available is that they will be sold including a tiny screwdriver for each light in the package plus a tiny useless Velcro strip. I haven't found a use for either, at least not with the lights. The Velcro can hold various cables that proliferate in any modern home. Every if I opt to change batteries, I already own better small screwdrivers. Just give me more lights for the price. And this package does that.

I got the blue because they are brighter than the red or green. I strapped several to the side rails of my dog stroller. The clips don't leave much space for the velcro strap, kinda over extends the clip, that's why some people complain that they break, plus the hold is not that tight. Putting some tape around helps to reinforce the hold, electrical tape works good because it's rubbery and easy to remove, but not practical if you're clipping to clothes. I leave the lights attached to the stroller. Each light comes already loaded with a button battery and a tiny screwdriver.

, specifically effectiveness for nighttime dog walks due to its brightness and long battery life.

They work as long as the battery's hold, to put new ones in impossible to get the screws out
