BLINK4 Mini Silicone Strap ON LED Bike Light - 8 Extra Batteries - 4 Lights - 2 Front & Rear Bike Light Set - Black & White

I wanted flashers for racing on roads open to traffic, but didn't want the added weight. These are quite bright for their size, especially the white headlights, and extremely lightweight. Great deal!

The media could not be loaded.  It not the best but better. Less money good service I can say. What I like here is they provided me product with extra one set Battery for each light. Another thing is this item programmed with three types of light blinking, so its convenient for anyone to choice right one. I am using these light for my baby's stroller at night time walking. It's really safe cz people / vehicle can notice from the safe distance to be careful early. I recommend people to use this item if you are cycling, walking with baby stroller or walking with your pets at night. It's a one kind of Safety gurd with less cost.

You'll receive a small, rectangular box which will include:2 black colored LED lights2 white colored LED lights8 extra batteriesBefore you install these lights, be sure to remove the red tab! I had to remove the silicone housing on some of the lights since the tab seemed to have been stuck. Which I found to be a good thing since I was already curious on how easy it was to replace the batteries. Come to find out, their is nothing complicated about the design of this product. Simplying remove the red tab, detach the silicone ring around the hook, apply the LED light on you bike handle bar( or whatever you choose to use this for) and reattach the stretchy silicone ring to the hook.On the top of the light, their is a soft button with three. One of the settings is your standard light, the other two settings are strobes with different intervals. I dont think I need to appear as a moving light house at night while riding my bike but the purpose is for others to be aware. so I'm glad to say that the brightness is very practical and I'm happy with this productIt is really reassuring to know that I can have roughly 50 hours of battery life but if you're willing to budget a little more I'd get rechargeable lights.You will easily spend more in batteries than you did on the lights.

Easy to attach. put one on my bike and one on the dog's leash so I can clean up poop in the dark. Light or dark you are supposed to clean it up people. this light helps. Also so far no cars have hit my bicycle since I added this light. did I mention it has three modes. full on (bright) blinky and slow blinky. good product and good price. cool they include extra batteries. I needed one for my guitar tuner so I killed two birds with one stone. I don't actually kill birds. stones are dangerous in the right hands. Not as dangerous in the left hands. unless you are left handed.

Good deal for 4 lights plus 8 backup batteries not to mention they got them to me like 24hrs after I placed the order fast shipping

The value for the money is overall good but the manufacturing is a bit poor. On the first use, one of the lights kept turning off after bumps. Being the rear light this could be a big concern. Luckily I was with a friend behind and he could alert me. I suspect the rubber enclosure it is not tight enough to hold in place the light and the battery causing bumps to shake the structure. Also the electronic is probably poorly soldered causing the on-off switch to be triggered erratically. Only one of the 4 lights so far had the issue as of now.

Added these to my and my wife's touring bikes in addition to the other front and rear lights we use to help make us more daytime visible.Unfortunately, they are very dim in the daytime. If you ride at night (we do not) maybe they will work for you but do not use these as daytime "running lights" as they are virtually invisible from any distance in sunlight.Also, one of the four we installed simply stopped working in either slow or fast Flash mode after about an hour of riding.EDIT: I raised rating from one to four stars because the seller saw my review and quickly offered to replace or credit me. Might not be the best item for my use but it came with GREAT Customer service and communications and that's always worth a lot of stars to me!

I bought these to go on a stroller and they are absolutely perfect! I use two in the front and two in the back and they can be seen at a very far distance. Neighbors have commented that they could see me coming a mile away!
