LED Safety Lights for Runners Clip Attach - Set of 2 - Night Safety Gear for Walking, Running, Cycling - Attach to Arms or Legs

I haven't used this much, but so far it seems like a fairly quality product. It is light weight and bright. It has three light modes, solid light, fast blinking light, and slow blinking light. I wish it had a "walking" blinking light, but all lights blink simultaneously. I tried to attach a video to this review, but wasn't able to.I unscrewed the back to see how difficult swapping the batteries would be. No problems. They even include a small screwdriver for this purpose, but I used mine, because mine allowed me better leverage. The batteries are lithium CR-2032 batteries. These are very common batteries. You might have them in your car keyfob. You can buy them in bulk on amazon. The trick is to BUY REPLACEMENT BATTERIES NOW, so you have them on hand for later. These batteries store well, so don't worry about them going bad in storage.The clip works well. I wish the light had a rubber seal against moisture, but it doesn't. It is only the tightness of the screwed-in cover keeping moisture out. So take the water resistance claims with a bit of salt.

These lights are excellent for the price. They are constructed well and very bright. Excellent for walking at night, increases visibility tremendously. These are a great little find. You even get a screwdriver to change the batteries when necessary

I bought this for my dog. It is the third set of lights we've tried. Usually she shakes really hard and the lights go out! These lights are very bright, the clip is long enough to slip over the velcro we attached to her harness and she is rally visible in the dark!

First set received had one unit that didn't work. Replacement set was sent and they both work fine.Great little lights for walking the dog in the dark. I can recommend

Bright light. It dose it job , good for running the grip on The little holds perfect to the shoes or back of your hat; so you dont have to be adjusting or fear you may lose it .. velcro straps ..mmm.. no so good, personality I dont like it .

They are bright, easy to attach and you can use either steady or flashing mode

I needed something more walking at night. These are great and get drivers attention better than reflective vests alone. Would also recommend for pet collars.

Arrived and was working right out of the box. Tried all 3 modes. Found places I would afix them. Can't wait to give them a real world trial run tomorrow.Changing batteries was a bit challenging. The screwdriver provided is a bit too small to generate enough torque. I used my precision screwdriver set and was able to unscrew all 4 screws reasonably easily. Then the back and clip comes completely off. Each light needs 2, CR2032 batteries.

Exactly what I was expecting. Easy to clip on. 3 light options. Just what I needed for running at night.

I clip 1 of these on my dogs harness so i can see them at night time

Perfect for what was required

Good light but the battery did not last very long at all.
