CECO USA 150 Lumen Super Bright USB Rechargeable Bike Taillight, IP67 Waterproof, FL-1 Impact Resistant, Pro Grade Quality, Red Bicycle Back Rear Light

Great battery life! I like the flicker options you get with this also. I found my 3 favorite flash modes. One manic flasher for day biking. One calmer flashing for night biking with little traffic around. Then one where it's always on maybe 40% brightness but flashes 100% brightness for busy areas at night where I need to be always visible. I feel a lot safer with this vs my old one I got for free from a friend. It ran on 2 AA batteries and had the old style LEDs. Not very bright. This thing blows that away but it's like comparing a scooter to a crotch rocket. Lol.

I never write reviews but I feel I must this time. I was looking for the brightest red tail light for daytime riding. One review stated how bright it was for daytime use. I was a bit skeptical but after receiving this light and turning it on I was instantly a believer. I mounted this light on the back of my helmet with no problems. I was so pleased with its daytime brightness that I immediately ordered two more. I will be mounting one on my wife’s rear bike bag and one on my bike bag. We have to ride a busy mile of highway to get to a side road and I feel much safer now that we’ll be seen during the daytime. This light has different mode options to pick from. The thing I like is you can turn it off without scrolling through all the modes. And when you turn it on you’re right back to your selected mode. I’ve tried several tail lights and this is the brightness I’ve found. It’s worth the price and it’s we’ll made for the cost. If you’re a serious road bike rider and concerned about safety like me you wouldn’t be disappointed

I'm very happy with the brightness and apparently rugged design. Of course the real test will be a couple of winters of commuting daily for 8 1/2 miles each way through salty slush. But it initially appears a lot more satisfactory than the last couple of rear blinkers I have tried on the winter bike. It looks like a real 150 lumens, very solidly visible from at least 1/4 miles away (about as long a stretch without bends in the road that I have on my commuting route). And it remembers and stores the most recent of the six or seven blinking modes that was used, so less of a nuisance to turn on and off than many of the lower-priced brands.

Nice and bright even on a sunny day to get you seen by drivers coming up on you. The mount is just a rubber strap with the piece on the back of the light made for a round surface. Many road bikes today have a flat back on the seat tube or an airfoil shape. Works OK on my flat back seat tube.

This light is easy to attach and is very bright. Easy to remove and recharge.

We do a lot of early morning cycling. My last light was good, but the rechargeable battery finally gave out. Well, found this Ceco light and it was considerably less expensive. It's a great light. Very bright, good pattern and the battery lasts and lasts.

My experience is that these last about a year. I commute yearround. Despite the claim of IP67, the charging port starts acting wonky after 6 months, and eventually charging fails completely. But it's a bright light, and the charge lasts well, so maybe that's as good as it gets for a product exposed to water and dirt to the degree that a bike tail light is.

Best light ever
