This should be on every bike. This flashing light is BRIGHT and will make your bike visible from behind day or night. It has several flashing modes, my favourite is the alternating red/white.It feels well constructed and easily attached to the seat post of my bike (I have it quite high) but it could also attach to one of the 'legs' of the frame. The on/off button is easily found and holding it down turns it off and remembers your setting. It comes with a USB C charging cord but if you are like me, you have serveral around the house. It comes with a rubber 'bungee' type clamp so it stays on firmly but is easily detached for charching.I have had several other rear lights, but this is indeed brighter than the others, and I like that it's rechargeable rather than using hard to find button batteries.Recommended.

At-a-glance (full review below):PROS:- Great compact design- Two colours of LEDs for different uses- Both sets of LEDs are very bright- Easy to install- Easy to charge, battery life seems fineCONS:- Only one unit in pack (the “DUO” seems to refer to the two LED colours, not having two units in the package)—— Full Review ——I was looking for a tail light for my new bike, and this one seemed like a great option since it could also be a headlight if needed.Out of the package, I was a bit surprised that there was only one unit, however this seems to be a misunderstanding on my part (the “DUO” in the product name isn’t referring to there being two lights in the box, but likely refers to the two LED colours). It would’ve been nice to have these come in a set of two, given that one could be a headlight or you could do dual-tail lights light shown in some of the photos.Regardless, I am very pleased with the lights! Having the option for both colours is great, and both colours are very bright (don’t look right at them from close-up!). While the light did come mostly charged, I did charge it fully which didn’t take long and was easy to do (the port cover doesn’t get in the way unlike on some other products, thankfully). So far the battery life seems pretty good, but we’ll see how it does as it gets older.Installing the lights is easy and I really appreciate the multiple different options which allow the lights to be suitable for different bikes or use-cases. The light seems to be well-made overall, so I expect it should hold up well.Overall, I really like this bike light. The price ($14 CAD at time of review) is exactly right, in my opinion, given the overall quality. I would highly recommend picking this up (or a couple of them!) for your bike if you ride at night.

This is a really handy and effective bike light primarily to be used for the rear but could be used as a backup on the front.The light comes with a number of modes but not all I would say are ideal. To turn it on, is a short press. The modes are: bright red solid, dimmed red solid, bright(ish) white solid, red flash, red S.O.S, red and white alternating strobe, then back to red (or the last mode you left it on, A long 2 second press turns it off.The reason I would state it is not ideal is that for a rear light is is perfect but if you are thinking of buying it as a front light, I wouldn't recommend the strobe function because it alternates with Red and white (no white only flashing), and when it is on solid white, it is not really bright enough to use as a main light in the dark, but I would use either of these modes at a push as a backup if my main light failed to get me home safely as they would be sufficient for that purpose.As a rear light however I would not hesitate to use it. I like the fact you can rotate it on the bracket so you can have it either vertically or horizontally to your preference, and the rubber quick attachment strap with hook will work nicely on a seat piller or fatter bit of bike frame (Although it won't be tight enough for using on some bikes with smaller tubes on the frame for the rear wheel.Because of the quick release and white light mode, you can use this as a torch or emergency light out hiking and the USB C charging means you don't need to worry too much about batteries as long as you remember to keep it topped up. Charging is via a standard USB C cable and didn't take long on first charge (and hour or so until the red charge light turned green). I can't comment on the duration of the battery but I don't see why it wouldn't last in strobe or flash mode for the 14 hours claimed.Overall though I am pleased with the light - it has a nice sleek look and will be a great addition to the back of my bike.

I'm not using this as a rear red light as I already have two for that purpose but I'm using this as a dedicated daytime running light on the handlebars - because they look so cool and the more visible I am with my daughter strapped to the bike the better!This is a fantastic light, actually better than the two red rear ones I already have. Most lights do not light up white as well and have the flexibility this has.Also, it rotates horizontal or vertical. Again not all do this, neither of my others do which now annoys me to the point where I may purchase another one of these for the back as I want a vertical strobe line up my seat post, not a horizontal one.The LEDS are super bright and I love that it looks like 1 long strobe rather than individual LEDs which look cheaper to me.It has the usual stretch type silicone strap which hooks on easily over different shaped bars.It charges superfast using USBC and according to the manual, will last 7h continuous as a white DRL which is perfect for my needs.One last key thing which is a deal breaker/maker for me now - it has memory. So find the setting you want, hold it down to turn it off. When you next turn it on, it's already on the correct setting. Also means you don't have to cycle through them all just to turn it off which is really annoying.It's a great product for £9.99 and highly recommend it.

Tail lights for your bike often tend to be cheaper, and I don’t know why. This single set of lights, being a penny shy of a tenner, is mildly concerning when price is a dictator of quality. I have a LOT of cheap backlights that glow red but lack the refined craftsmanship of the front lights - it’s possibly because we notice them less as riders?This light feels a little heavier than some of my others, although that might be because the strap is screwed onto the base. If you’re going to attach this to your bike, it has to be strapped on like a belt; otherwise, it must be manually unscrewed from its silicone ring. You can still twist it to a portrait or landscape orientation.Thanks to LED technology, having this on full beam brightness doesn’t cause the light to heat up. Thanks to USB-C charging properties, it also means up to a quoted 14 hours of lighting can be achieved in under 2 hours of charging, although of course, a brighter setting will lessen this.We’re also quoted IPX6, which means an unknown amount (X rating) of dust but a powerful waterjet of water (6 - enough for British weather) for protection against the elements.More often than not, you’ll have your light under the seat, on the seat pole, protecting from most splashes and grit with a mudguard.I like the packaging; I like the high-quality designs. I’m concerned their social media hasn’t been updated in two years, but so long as the battery holds up for a considerable amount of time in difficult conditions, I’ll be happy with these lights. The strap is a little thin and flimsy feeling but elastic enough that in most cases, it will make it around your pole.

These lights are easily noticed when flashing alternately between white and red like strobe lights. They last for a long time and are easy to take off and recharge. The only issue is that eventually the charging plug on the back comes loose making it impossible to charge them and I have not figured out a fix for this yet aside from buying a new one.

Very bright with multiple flashing options. Only downside is the light itself will not stay in position with the rubber mounting system it uses to attach to bike. I'm OCD and the light being crooked all the time bugs me

Lumen brightness is exceptional for such a small light with a wide variety of lighting choices. Would prefer the standard solid square strap insert rather than the round insert that came with it.
