GearLightRechargeable Bike Light, Bike Headlight and Tail Light Set, Powerful Front and Back Lights for Night Riding Safety, Night Riding Accessories, White Elephant Stocking Stuffer for Men

Small & lightweight but powerful biking light with several brightness / flashing options. Good for several hours of use between charges. The rear light is bright and powerful - I feel much safer riding with this set!

I bought these for my mountain bike about a year ago and they work quite well. The front light is very potent in the dark, even on the lowest setting. The red back light is great too, though I only always use the second mode. The back light can also be adjusted to go vertically or horizontally as needed. Both lights are easy to place and remove thanks to the rubber straps on them, and have gone through rain just fine.

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!

I just got the Gearlight S400 Pro a couple of weeks ago and here is my review based on a couple of weeks' use. Let me start out by pointing out that I am a keen or obsessive cyclist, safety light nut and battery geek. This is probably my fifth or sixth set of lights I have purchased from Gearlight for myself and as gifts for family and friends.The GoodThe longest I’ve used this so far is for a ride of 43 miles so we know it will last at least 5 hours in flashing mode. It rained during the ride (a lot) so we also know it's waterproof. Water beaded around the switch and on the top surface but the light never faltered.The red rear light is excellent. It fits the old Gearlight mount but has new LEDs and electronics with a new flash sequence.The front lamp has also done some off road riding on a MTB so we know its tough and absorbed a lot of shaking.It is BRIGHT. This is the brightest light I own and we only use it in flashing mode. No one has complained about being blinded… yet.The best feature, to me, is that it is repairable. I hate throwing things away when a battery needs replacing. All Gearlight front lights have been serviceable and I have changed batteries in all of mine of the older design (I am an electronics geek). This new one looks serviceable also.The Not So Good.It no longer uses the unclippable swivel mount.The mount supplied is now a rubber mount that needs to be detached each time you change bike or go inside at you favorite coffee shop stop or just drive home.When the rubber finally gives out that's the end of the light.The other bad news about this mount is that it will only permit mounting on the bars. No stem mount is possible as the light is secured to the mount with 2 screws so rotation is not possible. If your stem or fork is not vertical then your light will shine down or up.I would have been happy to pay a couple of dollars more for the old, adjustable, mount.Conclusion.Great light, bright, long lasting, nice features and serviceable. Can you live with the mount?

First, the headlight is good. Definitely does its job and it convenient to slap on your bike for a quick ride due to its rubber strap. No separate mount needed.But let’s discuss the tail light. Again, good light and it does its job. But just recently I saw it in my truck and it reminded me that I need to charge it. So I did. Charged it until the indicator glowed in green. Done. Took it off charger and turned it on to check it. It turned on just fine. It was on one of the strobe modes. Well all the sudden it wouldn’t turn off. It wouldn’t respond to a button push at all. It was stuck on that strobe mode. So that was now 112 hours ago. The light is still full strength and on strobe. It’s showing no signs of fading whatsoever. No, I have not put it back on charge or anything. It’s just setting on my counter and on. Again, it does not respond to a button push. It’s like it’s pulling from the electromagnetic charges of the earth to maintain infinite life. So even though it’s technically faulty at the moment since I can’t turn it off, it’s more impressive that it appears it will run forever. It’s fascinating to me. Thinking about starting a TikTok page just for this light and its journey. I’ll update if/when the light loses charge.

3* to now 5*, company replaced item with a new one. Light is bright, charges quickly. sadly the strap to put on and off the front headlight has broken.
