USB Rechargeable Bike Light Red or White LED glow or Flash 5 modes all in one Torch Flashlight Super Bright Taillight or Headlight for Cycling Safety set as Bicycle Helmet Rear Tail or Front Light

I like the ability to use as either a tail light or a white head light. Unlike another brand of light I have that is similar. This one is easy to turn off. The other is very weird. Although tiny this light puts out a nice crisp, bright light in either red or white modes. The selection of flashing modes is good too. Quick attachment and the ability to turn either horizontal or vertical is very nice. Should my primary headlight fail this little guy is a good back up too. I do wonder about the red/white flashing mode as it might be misinterpreted as a turn signal. Having worked at night most of my life I've seen some rather confusing flashing bike lights. They get your attention, but it is harder to judge distance and overtake speed. The flashing appears to be further away. Like an emergency vehicle on the next hill rather than a bike 30 yards away. IMHO, a slow flash is better than the strobe mode. YMMV

Bright...very bright....definitely worth the extra $ over the vast number of inexpensive lights out there. With the many different light pattern options, it's flexible as a front or rear light. Frankly, I wouldn't use the flashing white light (even in combo with the red light) as a tail light, or you might cause the driver behind you to overreact because it is so bright! Love the fact that this is rechargeable, but the true test over time will be to see how long the battery lasts between charges after multiple rechargesOverall, I recommend it for being seen even in sunny conditions.EDIT - didn't realize until after I ordered one more of these as a front light, that it has NO flashing white pattern. You get solid white, or flashing white/red combo. So I'm running white/red combo on front, which isn't recommended for a front light. :-(

I initially got a pair of these to use on the front and back of my helmet. These are very visible as advertised. I later got a second pair so I could have one set charged when I put the other set on the charger. One of these I accidentally got to change mode so it prefers white lights (modes are steady white, steady red, flashing white, strobe white) and works better as a front light - that's the only one of the 4 that can do a flashing white-only light. Other than that, the rest are better for back lights (modes are steady red, steady white, flashing red, strobe red/white). I wish they'd publish how that mode change is done because I'd like to set one front and one back each time I ride. I tried some combinations of holding the light for 10+ seconds like often makes a difference with other devices, but to no avail with this one. It also doesn't show any USB control interface when plugged into a laptop.

Super Taillight, Extremely Bright, Serval modes that conserve battery life and make you Highly visible. Well built, High Quality materials. Quality craftsmanship. Solid feel. We use this on both sides of our scooter, left and right to be visible to traffic while crossing streets. We also use this on the front of the scooter and the back of the helmet so that we are highly visible to oncoming traffic blocks away. Long lasting rechargeable battery. The rechargeable battery makes this a better choice because we save money on batteries. This taillight is used on a daily basis by my whole family because it helps make our travels on the busy roads much safer. This is not the most expensive taillight but in my opinion it is the best. When it comes to the down dollar cost verses what you get in value for each light available this taillight is by far the best.

I shopped around for a few different lights, and for the price this one is the best. I use them for the kids bike when they drive on the streets, the light is visible in the day, especially the blinking red/white setting. They have lasted for over a year, I have brought about 5 of them and plan on buying more now that my 6 year old is starting to ride the road. You can charge them with a USB and the charge lasts a few sessions. We also use them to go ridding at night as a head light.

Very bright. Multiple modes including Red, White, Blinking Red, SoS Signal Blinking Red, Alternating Red/White Fast Flashing. I purchased two to use with my electric scooter and bike. Comes with two handle-bar type mounts which can be used for a variety of installation types (I have them installed around a nylon strap on my backpack, for example), USB rechargeable. Highly recommend.

Pro: Light is functional & bright with multiple flash settingsCon: The strap that secures the light to the bike tore within the first month of owning the light. Two straps are included, and I can already see a tear forming in the rubber on the second one.If the straps were more durable, this would be a great value light.

Will see how it holds up. Very bright compared to others I've seen which is really nice. Does both red and white lights, with just the required options so you don't need to cycle through a million unused options.The internal body seems of decent quality but the external rubber is pretty lose and would stop some dust but I doubt would help much against serious rain, so we'll see how water proof the internal plastic structure is.At least for now, a good option for the cost
