Cygolite Hypershot 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

It's blindingly bright even in the day time you can see the light from 1/2 a mile , I had first seen this with a rider climbing up mt diablo and was impressed with its daytime performance so decided to give it a try.PROs:Many! to begin with its super super bright! @350 lumens!!!, it has a long lasting battery lasts my 100 miler without issues. Easy to mount and go , pretty good design suitable to mount on the seatpost not under the saddle like many a small ones out there. Also this is bright from the side profile and aptly right dimensions to be not too smallOnly CON is its not USB-C :(

I used this light for 7 days straight during an across state bike ride. The light is extremely bright and holds charge for hours! It performed well in rain, on gravel and pavement. Money well spent.

I ordered many types to decide which one is better. No one can beat this one ; it’s super, super bright.

Amigo muchas gracias estoy muy feliz con el producto la luz es de calidad muchas gracias

This is the brightest light I have seen. I like it enough to run two of them, one on each seat stay.

I owned a Cygolite Hotshot 100 for years and a competitors tail light before this. I keep coming back to Cygolite for a reason. Durability and features that are really used (some newer tail lights even adapt to braking which I find to be a gimmick), not features of limited to no use at all. For the reason of price alone, I chose the 250 lumen version of this light. The Hotshot 100 I had was very visible. It just took forever to charge. This light came with just above 50% charge and took less than an hour and a half to charge fully. We'll see if the claims of 3 hour charge time holds factual once i drain the battery to charging level again.Just two gripes about this light and Cygolite should be ashamed of itself. The seatpost clamp does NOT fit a 31.6 mm seatpost. They seem to be holding onto the smaller standard for seatposts. Thankfully, they've now made the standard for tail light mounts and I was able to use the old tail light mount to mount it to the seatpost until I get the T-mount I ordered specifically for my rack in and mounted. The second gripe is common to most bicycle tail lights. However, Cygolite still hasn't addressed their largest complaint. The charging port cover will not last more than a year at best even with the newer cover that I noticed. One of their competitors makes a better port cover, but not much better. Eventually, I'll have to replace it with duct tape to prevent moisture from entering at this point which is what killed the last Cygolite I owned.All said, I still recommend the Cygolite's. Headlamp or tail light. Their products will last even if you dump the bicycle while riding on wet or uneven surfaces. They are well worth their price. I only docked one star for the minimal gripes I had.

The Hypershot 350 is one of the best flashers made for use during daylight hours. The worst case scenario is when you are riding into a sun that's low to the horizon. The driver coming up on you is blinded by the sun.I've tested my Hypershot 350 by parking the bike on an east-west road near sunset and walking 250 feet behind it. The flasher was bright enough to be unmistakable in this situation but not by a wide margin. Less powerful flashers will be missed.The problem is that this flasher is much too powerful for use at night. Oncoming drivers will be blinded and provoked to road rage. Unfortunately, you can only adjust blink speed on the Hotshot, not brightness. I have a second and much less expensive flasher for use at night. It's the Blitzu [Amazon ASIN B00W7Y27CQ]. The Cygolite and the Blitzu are opposites in that the Hotshot is too bright for night and the Blitzu is not bright enough for day. It's ridiculous to need two flashers to cover the full 24 hours but there you are.The pricing on Cygolite products is very volatile. The Hotshot 350 is currently only 36 USD, which is less than the lower model Hotshot 250. It was 54 USD when I bought mine during April 2024.

Quality seems good.It is bright, almost too bright.Battery last for a long time.
