CygoliteHypershot 350 & 250 Lumen Bicycle Taillight Models–7 Night & Daytime Modes–User Tunable Flash Speeds- Small & Durable–IP64 WaterResistant–Secure Hard Mount–USB Recharge–Great For Busy Streets

I'm not going to attach a photo, because the listing already has large, high resolution pictures. Rest assured, I absolutely LOVE these Cygolite Hypershot 350 Lumen Bicycle Tail Lights. Having bought 3-4 different headlights, I became frustrated with the terrible quality, weak light, and poor battery life of the tail lights haphazardly packaged with them. Surely, I thought, SOMEBODY makes a high-quality tail light that isn't just an afterthought. Cygolite does.It is hot in Texas, so I ride my bike mostly at night when the heat of the day has subsided. Fast-moving, distracted drivers are dangerous enough without being invisible to them. The Cygolite Hypershot is bright. It gets noticed. Cars see you from far away. I can look over my shoulder and see it lighting up road signs 200 feet away. Settings allow you to adjust the light to blink and dim to your preference. Battery life is excellent. I usually charge it with my headlight, and the Cygolite battery outlasts it every time.I also bought the Cygolite Hotshot Pro 200. It is a slightly smaller, simpler design, but also an excellent product. You can't go wrong with either model. UPDATE: I just bought a second Hypershot 350 because my son needed a high quality tail light to ride with me.

Massively bright and conspicuous via an impressive number of selectable pattern and brightness levels. Pretty easy to mount to the support strut of my wife’s RadRover 2’s luggage rack, though I did need to dig around in my parts bin to find an extra shim.Looks like a top notch product, definitely a step above the Planet Bike tail light on my bike.

This is one of the brightest rear tail lights out there. Expertly designed, too/ May take a minute to familiarize yourself with the various settings. It is extremely bright at night. On a recent group ride, i had several people tell me it was blinding them. Then they asked who makes it?I had to study the settings to find out how to make it dimmer. You can only do this in two modes: Steady and Buzz Flash. The L button controls on/off and switching between modes. The right button will dim or brighten the light in those two modes.It comes with two mounts, for seatpost and seatstay. You can also clip it to a bag. If you want to mount it to a rack, you need to buy the rack mount, which needs extra hardware to fit on a Blackburn MTB rack. There is also a saddle rail mount available. I usually clip it to my under-seat bag, but I could also clip it to my rack bag or a messenger bag or backpack. AFAIK, there's no real way to clip it to the back of a helmet, except for maybe an aftermarket strap.It has some proprietary tech that adjusts brightness to meet different lighting conditions, which gives it a variable run time in every mode. I have no idea how this actually works, but Cygolite mention it in their marketing materials. It will also remember the last setting when turned on, which is a nice feature.If and when sheer britness matters, this may be the king of shine. It certain;y gives confidence in night riding that you will be visible in traffic. Just remember to dial it down if going on a group ride.

I use this same light on every recumbent trike I build. Every customer without exception has given them 5 star reviews for being bright, easy to charge and easy to mount. My only other comment is that you need to look at the catalog and decide if a different mount is more suitable for your application. Great, bright and long lasting. Who could ask for more.

Had the single lens version (I think 150 lumens) and decided to get this one as it is much brighter at 350 lumens. Different settings give different run times, up to 37 hours on the basic flashing sequence. I took one star off as it does not have USB C connector for charging, but uses the old style mini plug. Otherwise I am happy with this product.

The media could not be loaded. Purchased April 2023I ride daily in NYC, and *in* traffic, since bike lanes are often overcrowded with confused riders–arguably just as dangerous as cars at times.The Hypershot 350 is actually 1 of 2 rear lights on the bike (again, I ride in traffic). It is fully visible in daylight, and unavoidable at night. I have not walked back to gauge the total distance it is visible, but I have stopped mid-street on avenues and observe the red flicker on street signs *at least* 1/4 of a mile back. If you stand 30 feet behind it, it is practically blinding. Other comments suggesting its brightness looks like an ambulance from a distance are accurate.Received multiple comments from cyclists in daylight hours "wow, that is extremely bright" and "it was so bright I had to slow down and put more distance between me and you."Excellent visibility aside, there are two ways of mounting: a vertical clip; and a lateral (side to side) release of the clip itself. The latter is completely unnecessary, and the light fell off the bike mid-ride three times before I forced the lateral mechanism shut. No issues with the charging port cover, but I see the frailty of it may become an issue; be gentle or the rubber stop will come out, and you will pain yourself to reattach it. Too many lighting options; I only use two (random strobing, pulsing flash).Highly recommended. Absolutely makes riding safer. Waterproof.Video includes use of both the Hypershot 350 (seat post mount) *and Hypershot 150.

Lights up the night and day. Very good battery life. No problems charging. The only thing you have to watch out for is the cover for the charging port pulls loose. When it pulls loose, you have to take the light apart to readjust the water seal in order for it to work effectively again. Small inconvenience for how effective this light is.

Bright, good battery life. Many different lighting modes.Last multi-flashing mode I’d the one I utilize for visibility.Main con is that it charges through old slower style USB and not USB-C.

Light is strong with flashing options, battery life excellent, chargers quickly

Excelente luz, dura muchísimo la batería y el brillo es muy intenso

Really bright and love all the different strobe settings. Charges pretty quickly and holds a charge well so far.

This is the brightest rear light I've seen. It isn't just the 350 lumens number to look at, the spread and patterns of the leds emit a solid deep red light that can be seen from further away and it stands out more in busy city environments. It can be seen in the day easily and can be overpowering at night but that's what I wanted. The bracket is quality and doesn't slip or move and the quick release is easy but secure.

2 reasons why this is extremely bright. A is that it has a concentrated hotspot, ie very high lux (not talking about lumens). This is the value that you get on lux meters, the amount of light that you get at a certain spot some distance away. B is that it uses an orangey red emitter, easily 5-10 nm wavelength lower than other red LEDs. So your eye perceives it as brighter (brightest is at 555nm / green colour), more efficient use of power etc.I use 2 of these 350s as the hotspot is elliptical in shape and horizontally is 10 deg spread and vertically is 5 deg spread. So 2 of these gives me a 20 degrees horizontal coverage. I also use 2pcs of Magicshine Seemee 300 for even wider coverage esp with its additional Optic-trace LED firing sideways as i mount those horizontally on the back of my saddle (on a horizontal bar facing the rear).Need to fine tune a bit the vertical angle, the jagged teeth of the vertical angle adjustment is pretty "rough" and ends up either aiming the light too upwards or too downwards, esp for 1 of my light. I end up sticking some pcs of foam tape in between the clip on the light to serve as spacers so that the angle can be further fine tune. Very good light, you will be seen during day time. Use the STEADY mode for night time use, the intensity can be fine-tuned to a pretty low level. I think the run time for STEADY mode @ 350 lumens thereabouts (yes, full intensity) is 2hrs. This is one of the rare lights that you can run at max power in steady mode and still not overheat. AND also it can accept being plugged to a power bank and the light still stays lit, thereby prolonging the runtime a lot and limited by your powerbank only.
