4-Pack LED Safety Light Strobe Lights for Daytime Running Walking Bicycle Bike Kids Child Woman Dog Pet Runner Best Flashing Warning Clip on Small Reflective Set Flash Walk Night High Visibility

I clip these to my dogs' collars for walking after dark. The lights are bright and seem to last for a few months.ONLY COMPLAINT: Although very small screwdrivers are supplied with each light, it is essentially IMPOSSIBLE to access the battery casing with out almost breaking off the clamp. The ONLY light I was able to change batteries on was, subsequent to that change, damaged to the point that the clamp was bent and no longer capable of being attached to anything.In other words, these are sort of "single use" items, meaning when the batteries are depleted, they cannot be replaced--at least that has been my experience. I've tossed every one after the batteries die. (I've ordered six boxes of 6.)

These lights are perfect! I use two of them for part of my morning commute in the dark while on a scooter - one facing forward, one back. I purchased the green lights in order to be the most noticeable (brightest and nothing else on the road is a green strobe).I purchased a four pack, and one was DOA. I have contacted the seller (Umishi) to request a replacement battery - if they send, I will update this post.

Battery on one of them died shortly after purchasing. The other 3 are going strong.The strobe feature is great for early morning activity before the sun comes up.

if it was dangerous to run at night then i could skip it and wait till spring. These things make it safe and now i have to run. Ugh. Small but bright. Replaced an 5 year old similar one and its smaller but brighter

Great product and easy to use until the battery died in only a month of use.

OMG these things are BRIGHT!!! I bought them for my daughter and her dog after she got clipped by a car on her nightly run. I don't ever have to worry about her not being seen again!

I clip these onto my dogs collars when we visit the cabin. I turn the switch to steady glow or slow flash for my slow, older dog, and fast flash for my young runner. The lights lets me track where they are, and hopefully alert my gun-toting neighbors that there are dogs rustling in the leaves, not a wild animal.

Very bright. Has three different settings. Doesn’t stay clamped to my shirt when jogging like I wanted but able to clamp it to wrist band. Great for bikes.
