Ascher Ultra Bright USB Rechargeable Bike Light Set, Powerful Bicycle Front Headlight and Back Taillight, 4 Light Modes, Easy to Install for Men Women Kids Road Mountain Cycling Black

Has worked great for me, though I don't have to use them very often. They share the same charging port type, so you can use either cable (comes with two cables). The strap on the white light presses up against the body of the light, so it can be hard to slide it on the mount sometimes. Battery life has been at least a couple hours, though I haven't rigorously tested them. Works great for the price.

We bought this to install on an electric wheelchair for navigating crowds when outside after dark. This is perfect! We also bought a taillight to go with it. Great battery life and easy to install. Highly recommend!

Works well. Last decent time. Had in rain no problems.

The battery lasts about 2 weeks, with about 40min of usage everyday. Its pretty lightweight and compact for a bike i suppose. Has a few Power modes. Generally its a good value for an item.

Bought this item in 2023. I almost never have to charge it. It works Great!! Highly recommend. All of my bike friends recommend really $$$ bike lights. Mine works just as well as theres for more then ½ of the price.

The bike lights are incredibly bright, on par with more expensive alternatives. They provide excellent value for the money - definitely the best bang for your buck. The lights recharge quickly, which is very convenient. I haven't had a chance to fully test the durability and waterproofness, but the construction appears to be high-quality and durable. Overall, I would definitely recommend these bike lights. The only minor downside is that the wrap could be a bit longer to better accommodate thicker handlebars.

it's good

I REALLY wanted to like this headlight--and potentially there was I lot I COULD have liked about it--but ultimately, if you can't get the battery / charging system right on something like this, it's a waste of time and money. Also, the STRAP that hold the bike onto your handlebars broke the 3rd time I used the light... which was just a day or two AFTER the extremely short 30-day warranty on this piece of junk.I bike a LOT... and I've owned many different bike headlights over the years. So I have a bit of experience in these things. (Or, to put it another way, I don't feel like I have unrealistic expectations--and I have a pretty extensive frame of reference when comparing and contrasting cycling head-lights and tail-lights.) This set came with both a head-light and a tail-light--and since the tail-light so far seems to be operating fairly typically, I am mainly speaking here about the head-light.For the price, I liked a lot of things about this product. It was reasonably bright. The mounting system was good and easy to use. And it had the basic light modes you want / need when riding at night. The main problem is the battery. I don't know if these just have a bad switch--that is allowing voltage to drain the battery when not in use--or if the batteries are just cheap junk. But there is very little "stand-by" time with this head-light. Meaning you have to keep it plugged in / charging right up until you need to use it--or the charge drains out too quickly--even when not in use.For example, say you are going on a road trip and you want to bring your bike--but you might not be riding it for a day or two into the road trip. You pack up all of your cycling gear--charge up the batteries on your garmin, your head light, and your tail light--and take it all with you. A couple of days later, when you are ready to ride--you pull everything out and mount it to the bike and head out in the afternoon for a 2 or 3 hr ride--which brings you back at night. But, despite the fact that your head light was fully charged when you took it off the charging cable--two or three days ago--and you have not used it at all since--when you turn it on, it either dies fairly quickly--or already completely dead. A well designed and fabricated battery operated device should have a reasonably long standby time--so that when you're ready to use it--the batteries are still holding their charge.Another example with this light: I charge it fully, go out for a ride--say, for 1 hr--and I use the light the entire time. I turn it off when I get back home and leave the light on my bike--for the next ride. The manufacturer claims this light should last for FIVE HOURS on full bright without needed to be recharged. Which means that I should have FOUR hours left on the batteries at full bright for my next ride. However, even if I ride the next day or within a couple of days, this light is always DEAD when I try to use it a second time without re-charging.(FYI - I just tested / timed how long this light works on a full charge at full brightness--and it was only about 3 hrs... NOT even CLOSE to the 5 hrs that they claim here in Amazon. Which certainly does not surprise me given the other batter issues I've had.)So, in my experience with these types of things, that means either the power switch is bad--and the bulb is bleeding a tiny amount of power from the battery even when in the "off" position--or the batteries or charging system are no good--or a combination of the three.I bought this light mainly because it was small and easily / USB rechargeable--and easy to mount and dis-mount to switch between various bikes (because I have many, many bikes). I already have some bigger / brighter / heavier lights--that are more complicated to mount and dismount--if I really need to light up the night. But since I can't trust the battery / standby life on this light, it renders it much less useful overall.I bought this to replace a Cycle Torch light I used for quite a while--that I loved--that fell off my bike and got run over in traffic before I could safely get back to it on the road. I almost wanted to cry when that happened--because that was almost the perfect bike headlight. However it is nearly 2x more expensive than this Ascher--though also 200 lumens brighter (I think). (I can't find a specific lumens claim for this headlight in the Amazon listing details... but when I searched the "Q/A section just above the Reviews, someone answered that the headlight was 300 lumens; the Cycle Torch Shark is stated at 500 lumens on Amazon.) Though the battery life on the cycle torch was definitely getting weaker over time (I had it / used it for many years)... I never had this problem of it going completely dead in a day or two if not used--after fully charged. Even the brand new Cycle Torch on eBay only claims a TWO hour run time on "high"... which is honestly pretty similar to what I was getting / expecting from my +/- 5 yr old version. And, compared to the only +/- 3 HR run time for this Ascher head-light... which is supposedly 200 lumens less... 3 hrs sounds about right. (I never believed the 5 HR claim.)So, right now I'm trying to figure out exactly how to contact the seller to file a warranty claim for this head-light. They don't SPECIFICALLY mention a warranty period or process ANYWHERE on this Amazon page for the product. But I'll try contact them directly to see what they say... if that is even possible. (Update: Turns out it is not possible at all. Essentially, the ONLY warranty / returns available on this light are during the initial 30 day period after you purchase it--that virtually ALL items purchased on Amazon have. So, be aware when you buy this headlight that if it fails after just 30 days... you're out of luck. Thanks, Amazon.)
