Bicycle Tail Light LED Safety Light (4 Pack) Bike Rear Light LED | Clip On Strobe/Running Lights for Runners, Dogs, Bike, Walking | High Visibility Accessories for Your Reflective Gear, Bicycle etc.

I bought these for my dogs' collars so I could see them in the yard at night if they weren't tripping the motion-activated lights. I absolutely love them. The lights are super lightweight and I just slide the velcro loop onto their collars. They have assigned colors so I know who I'm seeing when it's dark. :-) The lights don't bother the dogs a bit, but they are nice and bright so I can see them when it's pitch dark. This set is also a great value. We received one blue, one green, and two red lights. All had batteries in them PLUS there was a package of 5 or 6 extra batteries included. I would highly recommend this product!

Product works well (2 red, 1 blue, 1 green lights). Love the brightness of the lights. Will be used in early morning runs and people can see me from quite a distance. Highly recommend !

These little lights have been great. I often need to walk the dog later in the evening/night and these have been awesome. There are 4 lights in each pack: 2 red, 1 green and 1 blue. I put one light on my body and 1 light on my pup. I have had them several weeks and I use them every night. There are 3 light "modes": constant on, fast-blink, slow-blink, and of course off. They are very bright. I have used it to shine as a flashlight to get my mailbox key into the slot, at night. Very effective. I have not had a need to change the batteries, but if I do need to change them, there were spares that were sent in the original box. Nice!! I don't know if they are water resistant. They are small enough that they do not get in the way. My dog is on the smaller sideand does not mind the "weight" of the light on her leash/collar.

Lights give visibility to on coming traffic. Very bright. Good quality.

It gets dark so early in winter and I was nervous about walking the dog at night. These lights attach to my dog’s winter coat. I appreciate the option that allows them to flash because I think it is even more noticeable than a solid light. I think we are both safer while crossing the streets.

These are ok. They are not very bright, and the clip is not strong enough for small bumps on the road if used for cycling.

Small and light weight! Perfect for walking before day break! Great price!

They even come with batteries. Just clip them on your clothing or bike and you're good to go.
