Cygolite Hypershot – 350 Lumen Bike Tail Light– 7 Night & Daytime Modes–User Adjustable Flash Speeds- Compact & Durable–IP64 Water Resistant–Secured Hard Mount–USB Rechargeable–Great for Busy Streets

Best rear daytime light you can buy In 2025….Cars now have entertainment screens 15 inches across. This kind of distraction raises the bar to be struck by a distracted driver…. This ultra bright tail light gets you noticed. Don’t cheap skate yourself on safety. Dependability……My oldest 350 is almost 4 years old. That 4 years equated to 200/300 kilometres per week of road time. My 4 year old light is now holding a charge for 90mins. The pouch battery inside is replaceable. You will require soldering tools and the skill to use them. I however have bought new lights for the longer rides. Riding tip. In the winter I did wrap the light in cling wrap then slide it in the mount. 4 years and still working speaks for itself. One last tip…. If you purchase the under saddle mount use a removable thread locker. Even hot glue is better than nothing. I luckily doubled back and found my light. Cheers

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.

I don't bike much but realize it's important to be seen both day and night. I have witnessed people on bikes without lights or lights that were so dim during the day that i thought why bother; one I believe was even a "brake light" type of rear light that barely got brighter when stopping - this is not dim. I haven't used it on the bike yet but indoors this light is bright; it projected light at least 25 feet with a large spot of red light on the wall. It can change speed of the flashes in flash modes and the light brightness for the steady on & buzz mode; I'm thinking that even at the lowest light brightness if another biker is behind you it'll be too bright because of the way it projects the light.. I bought it for the daytime flash mode, the ability to change the brightness and flash speeds. It has a clip to put it on a bike bag that's mounted behind or under the seat (have to hold keys somewhere! :-) ). It came almost fully charged but I did have to top it off but it was a quick top off. It seems to be a well built product and hopefully it'll last a while. I know there are higher lumen taillights than this one but if this projects as well outside in day light as it did in the house it''ll be a great taillight.

This is a good taillight - bright with many nighttime and daytime modes

Excelente produto, super top, recomendo demais da conta sô. Não é barato, mas vale muito a pena.
