Bike Tail Light USB Rechargeable by Apace - Super Bright 100 Lumens LED Bicycle Rear Light Easily Clips on as a Red Taillight for Optimum Cycling Safety

Mounting: I am a very petite female, which means I have a very small frame bicycle. So I can't mount a light to the seat tube (saddle bag takes that entire space), and potentially am also unable to clip a tail light (if it even has a clip) to the saddle bag (quite a few lights hang far enough down that they occasionally hit the tire on bumps). So a tail light primarily designed to mount to the seat stays is ideal (for me). And can also be easily swapped between bikes whether they have a saddle bag or rear rack or neither. (If you want a light to clip to a saddle bag, this wouldn't be a good option, but should work fine on the seat post). Reliability: I have found that very, very, very few tail lights reliably stay on for the entirety of a ride. (They don't run out of battery, just randomly turn off, possibly due to something momentarily disconnecting during bumps). I've used this light for at least 5 rides now, and it has still been on at the end of every ride I've used it on. (In comparison, Cygo and Ceco's seat stay tail lights both failed miserably here, and were promptly returned to Amazon). Battery life: I've used this light on multiple rides without recharging it, and it didn't die (which isn't true of all my taillights) so I don't have to worry about whether I'm able to or remember to charge it between rides (useful, particularly, if riding multiple days on a camping trip). I haven't fully tested the battery life, so can't speak to exact amount. Brightness: The high setting is pretty bright - not the brightest, but far from being weak. The lower setting seems to be an ~perfect compromise between not blinding other riders and not being ridiculously weak. (I found Cygo's version to be too bright on the high setting for group riding, and pathetically weak on the lower setting). I would definitely recommend this light for anyone not looking for a clip-on tail light. And I would definitely strongly recommend it over its competing name brand lights

This is one of my all-time favorite tail lights. Clever, reliable, durable bands and fittings make it fit pretty much any rear rack or seat post. There are many modes to click through -- flashing modes of varying speeds and brightness, a pulsing mode, and some steady modes, including blazingly bright. I turn on this light whenever I have to ride at dusk or near traffic. Even in broad daylight it gets attention. Charges quickly via USB cable, indicator turns from red to green when fully charged. Great customer service, they reply quickly to queries.

I bike often. Unfortunately, even with wearing bright clothes and having fancy brand name blinky lights front and rear, I am still invisible at times on the road. To up the "can you see me" factor, I have added lights front and rear. The company that makes this exceptionally bright red light, also makes an obnoxious white light for the front of the bike (obnoxious meaning in strobe mode it hurts the eyes if looked at for too long). After using that one in addition to the other brand name light on the front and have had much success with it, I decided I need another obnoxious red light in the back of the bike. Ta da - exactly what my bike was missing. This red light is easy to use, mount, and charge. Mine is mounted on the seat post below the reflector, within reach of turning on and changing the setting. Well worth the cost. Long lasting too. Although, I charge all my lights after 3 rides (most rides are 2.5hrs), so I have yet to witness this light or the front light run low on battery. Highly recommend and yes, I would definitely buy again.

I've been using this light for almost 2 years, and it has never failed me. It's very bright-I use it on flash, and it makes me feel safer and much more visible. The mounting system and rubber on the back make it versatile and easy to fit it on a number of different surfaces, i.e., seat post, rack, etc. The battery lasts multiple, multi-hour rides, and charges easily and quickly. If I needed another tail light I would buy this one again in a second, with no hesitation. Highly recommend.

See Five year review update at bottom... Form and function: First if you have an aero seatpost, the included mount pads might not be ideal. You can probably find a way to make it mount. It's also a bit too large for most seat stays and it doesn't easily mount on saddle rails or saddle bags either. Anything is possible with some creativity, but it's really best for round seat posts. It does include plenty of mounting pads and bands, and a nice little pouch. To me the slightly large size is good. It allows high total ouput without high pinpoint intensity when viewed up close. That's less blinding and easier to focus on and locate, while still just as visible at a distance. It weighs about 52 grams including the pad and band. It seems pretty rain proof. It generally looks and feels like a good quality gadget. It charges fully in about two hours (I didn't monitor it closely) consistent with 0.5A charging claims. The daybright mode is very nice, very visible in the daytime. My riding buddies commented on seeing it far up the road in the daytime. I think it's using the full 100 lumens, or a good fraction of it, in short pulses to get attention and last long. I wouldn't use that at night. The pulse mode is interesting for night. I am not a fan of blinky modes at night, but pulse dims and brightens smoothly without going off, improving ability to focus on the light while still getting some improved peak brightness without all of the runtime reduction of a steady bright mode. Mode claims: It comes with a manual with these modes listed: Low 12 hours Medium 6.5 hours High 2 hours Slow flash 45 hours (a standard on-off flash, low power) Smart flash(TM) 7 hours (Similar to Slow flash but brighter) DayBright Flash(TM) 15 hours (Short high intensity pulses) BritePulse(TM) 4.5 hours (Pulsing wave pattern in time, never off) Performance testing: The good: I've actually done some fairly quantitative testing on this light. I have no absolute reference, but on high I measure it about twice the total output (scattered light from all directions) of a 50-lumen claimed moon MK-II, and has a similar beam pattern. That's a smaller and lighter-weight light that fits on seat-stays and has lower claimed runtime and obviously brightness. Both lights drop off in brightness some as voltage depletes, dropping to about 70% eventually. It's pretty common for lights not to have true voltage regulation, which requires a little more electronics. The medium steady mode is about 1/4 the output of the high mode initially, and the low mode is about 1/8. This all seems fine and in line with claims relative to at least one competitor. Also I tried to test the daybright mode but not using suitable equipment for pulsed output. By eye, close up, it appears not as bright as the high mode, but perception of fast pulses is complicated. I was able to get readings that weren't far off of full brightness in spite of not have fast triggered sensors, and as mentioned it's very visible from a distance. The ugly: After 20 minutes on the high steady mode, aside from the initial voltage-related drop to about 75% brightness, it also steps down again to about 75% of that from a hard-coded timed step-down, and it steps down by a little over twice again after 1 hour and 20 mintues, reaching about 20% of its initial brightness at that point. I get a total of almost 3 hours of runtime before switching to the battery saving blink mode. That lasts about 1.25 hours (they claim 30 minutes, and I'm happy that it's longer). The two steps are not thermal or voltage related. They are just hard-coded timing steps and it would seem they exist to extend runtime while still getting the initial high lumen output. The step downs are even done in multiple steps a few seconds apart, making it less likely that you'll realize this. If I reset the light after each programmed step down, it follows a similar output curve as the Moon light, and gets a runtime of 1.5 hours, not the claimed 2 hours. As it stands the high mode is like a "turbo boost". You set it when you need to get through a few miles of dense city traffic but it will drop back down after that. To me, that seems a bit like cheating on runtime claims, or at best not explained up front, and I also just find it as not an ideal configuration personally. If I want to use high for a short time I'll do that and if I need low for a longer time, I'll change to low. To their credit the customer support manager has been very responsive and sympathetic. He did discuss with their manufacturers and verify the issue, and I think he's sincere in saying he wants to fix this. I don't think they can fix it and still get a claimed 2hr runtime on high. I think at 1.5 hours, it's still a great light, especially at this price, but they should remove the step downs. In their defense, their most direct competitor (over three times the promotional Apace price) has the same battery capacity and their claimed runtimes don't add up. It seems they may be doing similar tricks, and I understand the need to compete to sell lights. Overall: A long running light with great day and night capabilities, especially for the price, but some limitations in mounting options and some unecessarily dubious performance claims that might not hold to up to what you'd expect from the description. Customer service seems sincere in addressing it, and the light can still be a great buy, especially at the promotional price of about 3x less than the competitor. Five year review update: I have used this light probably six days a week for five years. Although I never re-measured it, it still had good run times. After about 4 years the usb c plug broke off of the circuit board it attaches to. After cracking the glue to open the light I was able to fix that and re-seal it. This can be avoided by avoiding stress on the plug when charging. I often charged it on the bike with the light twisted to expose the plug, but creating a little pressure. It's not super strong though, and thicker solder connection to the plug housing (which I added) could have improved this. But now after 5 years, it won't charge anymore. This appears to be a different issue as the usb connection is still solid. The light operates after first bypassing the board to charge the battery manually, but the usb charging circuit seems dead. Anyway, 4 or 5 years isn't bad, so I bought a new one.

On my 3rd version of this tail light. (The first was stole. I carelessly stripped it off the bike on a ride. My bad.) I always research a bit, but have always come back to this light for the price and performance. Sleek fit that blends aesthetically with the seat tube. Holds well. Able to reach down and turn it off or on during my rides, which I do from time to time. Brightness is just right. Battery has never been an issue as I re-charge before any ride. Visible from the sides. 👍 I wish it made a loud clicking noise when the button is pressed so that you know the switch press was good, especially on those blind attempts at turning it on/off. The button could be a little more pronounced (ie taller) to give it better tactile feel when pressing.

This light is easy to mount to a bike and comes with a large variety of mounting rings (like large rubber bands), making it easy to mount to various sized bike frame tubing. You do have to remove the light to recharge the battery. The light is exceptionally bright and can hurt your eyes if you stare directly at it. The on/off switch is on the side and takes a 2-3 second push to turn off or on. It seems to be well made, and has several power and blink modes. I’ve only used it for a short time but it seems like a great light.

When they describe as super bright that is exactly what it is.....super bright. It is not intended to be looked directly at from a short distance away like when you first turn it on and want to look and see how bright it is. Use some caution. It is re-chargable, has several extra rubber attachment bands of different sizes for you to be able to find a spot on your bike to attach. Usually they are placed on the seat post facing backwards. I ride with a tool pack attached under the seat of my bike so there is no room for this light because it mounts vertically in the long dimension and my seat post is not extended enough. I attach it to the seat stay on the left side of my bike. Not ideal but so far it has stayed in place.

They didn’t fit on our bikes so now we have no back light.👎🏻🤦🏼‍♂️😡😢😤

Wow, I laughed at the one reviewer who said you could see this light from the moon, however once receiving it, wow, I think I partially seared my retinas and I didn't even look right at it on it's brightest setting. This light is amazing. I have it mounted on my seatpost and I always use the ultra-bright-fade-then-back-to-ultra-bright, constant repeat, setting. I only ride during daytime hours. I have ridden with this light during light rain and have had no issues with water ingestion or lens fogging. On the setting I use it on (see above) I get approximately 7-8 hours of use before I need to recharge it. I am a little weary of the thin rubber bands they include with the light to secure it to your bike. I do like that it is very quick and easy to remove (so you can take it with you and throw it in your backpack when you lock up your bike). I just am worried that the band will eventually snap from use and now my light is gone who knows where. I have lost lights before and never once have I heard it fall off so I have never recovered any lights before. For my piece of mind I have two bands securing this (overlaid) to my seatpost in hopes that I won't ever lose this light. I love the light, very bright and easy to recharge. No more wasted batteries being replaced.

Light stopped working or charging after one use

have used this a few times a week for about 2 years. initially was sceptical about the fixing method but it is actually fantastic. Very quick to put on and off (twist the band around the light to make sure you dont lose it - there are spare ones but you would be stuffed witohut one). Extremely versatileand secure mounting - you can always a find a way to fit it to the bike or saddlebag/rucksack etc, so that it is still rear facing, whcih isnt the case with the more standard thick rubber tags, this is really useful. the light itself has 6 sensible settings, the flashing onese are suffucently quick that you wont be missed if a driver monetarily looks away.. thoroughly recommed this rear light. Never ran out of charge whilst using it for commuting and rides an hour or so long(not so keen on the front one though - doesnt cast a beam any substantial distance as it is so widebeam, fine if thats what you want i guess, , also hard to stop it shining in your face if it is handlebar mounted)

Ho acquistato questa luce posteriore assieme a quella anteriore. Devo dire che dopo 2 settimane di utilizzo sono assolutamente soddisfatto e mi sento di consigliarla a tutti. La luce ha diverse opzioni di luminosità, fisse e a flash. Ci sono tre opzioni di luce fissa da più soft a più potente e devo dire che la più forte ha una luminosità veramente intensa come si vede dalla foto. Inoltre ci sono svariati accessori di montaggio di varie dimensioni per cui non è stato assolutamente un problema montarla sulla mia bici. Il fanale rimane fermo e non si sposta. La batteria dura a lungo e non ho avuto problemi in nessuna uscita anche con un po' di pioggia.
