OLIGHT Seemee 30 C Bike Light 30 Lumens Tail Light 230 Degree Visibility, 800m Viewable Range, USB Rechargeable Bike Break Light, IPX6 Waterproof, Road and Urban Cyclists

This thing is way smaller than I expected. The photos make it look a lot bigger, but in person it’s tiny. That said, it’s built like a tank. The body feels solid, and the rubber strap is thick and tough. Honestly, it feels overbuilt in a good way. The brightness is great, especially for how small it is. Super easy to clip to my seatpost. The only thing I didn’t love is the little rubber bumper on the back that covers the charging port. It’s not attached, so it pops off every time you go to charge it. I ended up gluing one side of it down so I wouldn’t lose it. Other than that, it’s a great little light. Super handy and clearly made to last. Definitely would recommend and buy again.

Who's ever heard of Olight? Not me! It sounds as weird as Anker... clearly, that brand is going nowhere with that name... Manufacturers are innovating, releasing their own brands, and Western companies that we've relied on for quality rest on their laurels, fall behind, and are failing to innovate... Anyway, this thing is pretty cool. Fast USB-C charging. Simple but solid construction = less likely to fail / break and also lighter. Rubber back stays put on seat stays or the seat post, and come off to reveal the USB-C port when you want to charge. I haven't pushed this to its limits but I can ride about a week (6-10 hours) before I decide to charge it. 5 settings with nice solid LED lights that aren't painful to look at or blinding for cyclists behind you but visible enough for cars to see in daylight: - Solid low - Solid high - Bright blinking every second (what I use most often) - Less bright blinking every second for three seconds, then pausing for one - Solid low with blinking high every 2 seconds

Almost 5 years now using this and still like brand new! Appreciate the brightness and longevity of the battery....I can't believe it has lasted this long, thank u !

I trust the name and I love the size and quality of this little light. Very bright last a very long time, I have two on my bike. This light would be. A five star light if the rubber cap on the back didn't just fall off every time I took it off my bike to recharge it. Why did you pick this product vs others?: Olight is a good reliable name, I use a number of different tactical lights made by them, So when I got back into bicycling It's perfect the brand that I trust makes lights for my hobbies. Flashing mode: Didn't come with All the flashing modes advertised on youtube Like the breathe flash mode. Both my lights won't do that setting. Battery life: Always outstanding. Ease of installation: Beware of rubber cap. Size: Perfect. Bright! Weight: Feather.

Works great. Nice and bright

The light is of a higher quality compared to other bike tail lights on the web. This is a higher end flashlight brand that made a good quality bike light. I put them in the same category as Fenix. The light mounts easy, works well and great battery life. I never have to worry about it running out on a night ride. My only complaint is the different flashing functions. It has three modes and two of them are a "breathe" type flash that are not very conducive to catching attention of motorists. The flash function (the one I use the most) is a very quick flash that does not seem to utilize the full brightness of the light to it flashing so fast. I wish it had a slower flash function or one with a non-rhythmic flash that catches the eyes of car drivers. I use this in conjunction with a helmet light, and have been told by other riders in my group that they are a good combination and attract attention well.

Kinda hokey mounting system - basically a rubber band to fit around your seat post. Lightweight, yes. Secure, probably. Long lasting - perhaps not. Output probably as stated - 30 Lumens, so more of a marker light vs warning light. Claimed 230 degree visibility is believable, but light level definitely falls off the further from centerline you get. If weight is main criteria, not a bad choice.

Easy to use, brightness is more than adequate in various conditions (heads up--don't look directly at the light when you first charge and fire it up--it's bright), and utility is very good for steady state light or flashing. As is usual for products coming from overseas, instructions are not the most detailed, but you get the flow after a few minutes. Battery life appears to be solid so far. Long time road biker, I highly recommend. The price point is good. Postscript, a few weeks after this review, the light stop taking a charge. Tried various troubleshooting methods and let charge for extended periods. No go. The light flashes for a second and then off, with charging light briefly lit and then also off. The return window closed a month before malfunction.
