Bike Lights for Night Riding, USB Rechargeable Front and Back Lights, LED Bicycle Headlight and Tail Light Set, Water Resistant Bike Lights Rechargeable for Mountain Bikes, Kids Bike Light, MTB Light

Second update 2/8/19: I unexpectedly received a replacement set of lights from GearLight. They included a MUCH longer screwdriver. Nice suprise, but I was still skeptical. The screwdriver worked with the replacement lights, but I didn't know if they'd hand-picked a light set to send. But I had one light left from my original set, and the screwdriver worked well with that. I took the back all the way off and put it back on to be sure the whole process would work and it did. (One review talked about the clip being an issue, but it wasn't at all.) So, IF the new screwdriver style is included, I'd definitely give these a five star rating. They're super bright and the two flashing options make me much more comfortable that my dog and I will be seen when walking on dark streets. Update 1/12/19: I've had these a little less than four months and the batteries are now dead. I tried to change them with the screw driver included and the screws simply won't turn. Tried a different screw driver with a longer handle, pushing hard while turning, etc., but still no luck. So basically these are over-priced throwaways, prior review: These are under an ounce each, but nice and bright for being seen while running or walking in the dark. The clips grip well and are easy to use. Each light is 2 1/4 inches high and comes with its battery installed, but you get four extra batteries too. I like having a choice of steady light, slow flash and fast flash (but I probably won't use the fast one). I walk or run my dog twice a day, plus take runs without him. There are no sidewalks in my sub, so visibility is extra important. I have a reflective vest, and so does my dog, but I feel a lot safer with two of these on each of us! I don't normally order things on Amazon that only have a few reviews, but these were cheap enough that I thought I'd give them a try. Glad I did!

Very bright easy to use battery lasts a while

As expected just haven't got the bike to test them, very bright and I feel like ill be very happy with them

I use this for walking at night. The velcro bands are too small for my arms. Too small even for my teen daughters. But the clips are well designed and have not fallen off my jacket or hat. The lights are bright, so even though they are small, I am easily noticed. I wear two at a time, one at the fast blink, the other at the slower blink. My neighbors have commented they easily see the lights as I am walking. Oct 18, 2019 - Work changed, I was walking in the day. Another change, and I am walking at night again. I pulled these out, the green ones were still bright. The reds still turned on and flashed, but they were not very bright. I still had the screwdriver, but either used or misplaced the spare batteries. The units each take two CR2032 batteries, which are pretty common. The screwdriver from my set is the short one, about 1 3/4 inch. Notes from other reviews say it now comes with a longer screwdriver. The screws are tight, but I only struggled with one. It came out when I put my finger on the end of the screwdriver, so I could put max pressure down on the screw. I then turned the unit to get the screw started, and it came out properly. The screws are tiny!! I dropped one and needed a magnet to find it. Note how the batteries are flipped when you open it. There are markings how the batteries should be placed, but they are not clear. It reassembled without a problem, and now the reds are bright again. I still recommend and give 5 stars.

Excellent price at $15 for 4 lights. Excellent for running. Sturdy, looks water resistant. Not rechargeable, however they run on the large 2032 button batteries which you can buy at any grocery store or Target. You can put one on your kids back to find them at evening gatherings. The clip on lightsf might not be the first choice for a permanent installation on your bike, but easy to pop onto a rental bike or kayak. I dig the low price concept and admire the quality & design.

The lights are the right size but battery powered let’s see how long they last. However they look good on my ebike.

Great brightness. But, not rechargeable - not worth the price because there are cheaper ones that are equally bright that are also not rechargeable

I bought the set of four and one arrived without the screws that hold it together. I contacted customer service via email, someone replied in less than an hour, thanking me for buying their product and wanting to correct the situation. They asked for an order ID number and a photo if I had one. (The one included here.) Two days later I had a new pack of lights as replacement. By the way, I love the lights. They are bright, have three modes (steady, strobe, flash), come with elastic bands for wearing them, replacement set of batteries and a tiny screw driver for the tiny screws in the units. Each light has a clamp with teeth to hold the light in place. I clamp them to my dogs when I walk them at night and they stay it place well. I can't comment on battery life at this point; each light uses a 2032 battery. So far, a good purchase and a good company to deal with.

I had received the product as scheduled and after 4 weeks the light died on me and could not switched off. When we opened the lights they were full of rust. This order was delivered by a reseller from China. I placed another order and I received it from India. Please note that the picture on amazon does not match the actual packaging which created a lot of problems when communicating with GearLight. These lights are the most expensive positioning lights I have purchased but they died miserably full of rust but Gearlight issued a refund ...no questions asked. I am a long distance runner and I must have reliable lights. Hopefully the one from the reseller based in India are a bit better

These seemed expensive at first, but after receiving them I realized they were built very well. The LEDs are very bright and should last a long time, and the units, including the clips, are very sturdy. They also come with good quality Velcro straps to fasten to bikes, strollers, etc. Recommended.

Use them when we take the kids out in the park for biking. The lights indicate when the kids are when it is dark. So we don’t have to worry about losing them in the wood.

4 in a pack, one never worked, other 3 same problem pin that holds the clips pops out and there is no way you can put it back as theres a spring inside you cant see. all clips broke. Great led light but extremely cheap way holding them clips. For 30$ plus shipping and all, didnt last a month.
