Best bike rear light I've tested. I've mounted just under my saddle. What's the best part is that the light will automatically turn off once there's no movement for 30 seconds and then start up once it detects movement. Coming home I don't even have to manually turn it off. Set and literally forget. Add to that that it literally sips electricity and it has an on-board percentage gauge... it's the best light I've ever tested.

The DARKBEAM Bike Tail Light delivers an impressive combination of brightness, durability, and thoughtful design, and it immediately stands out from the usual budget tail lights. The LED display screen is sharp and highly visible, even in bright daylight, and the defined patterns make you noticeably easier for drivers to identify at a distance. The six lighting modes are distinct and practical, offering real flexibility depending on traffic and lighting conditions. USB‑C charging is a welcome modern touch, and the port cover seals securely without feeling flimsy. Battery life has been consistently strong across multiple rides. The IP55 weather resistance held up well during dust, light rain, and post‑ride rinsing, with no flickering or moisture intrusion. Instead of a silicone strap, this model uses integrated hooks designed to fit under the saddle rails. Mounting was straightforward; securing it with cable ties created a stable, rattle‑free setup that stayed firmly in place even on rough surfaces. Overall, this is a bright, reliable, and well‑built tail light that offers real functional value and a noticeable visibility upgrade for anyone riding in traffic or low‑light conditions.

These little byclcle tail lights are interesting. They appear to be well constructed and all of the functions work as expected. I mounted them on the bikes. No brighter or less brighter than the previous ones I use as rear side markers on one of the bikes now but it really seems like that motion activated braking action thing is really going to work. They came 100% charged. I like the little seat brackets. Have them zip tied nice and tight. Let's see how long they last. I'm captivated by them either way and they are worth the money just based on that.

Decent overall. I do like all the different patterns and that it has the LCD screen to show the current percentage. The brightness is a okay, during the daytime it’s really only visible on the single blinking setting. For the price, that’s kind of expected though. The different mounting brackets give several options for installation which is nice.

Out of the 4 that I received one was broken. The switch is not working. However, I like the usb-c charging and the ease of use and they are reasonable bright. They work great on my Dog trailer

Bought these for my kids bikes for dusk/evening riding. They are highly visible, have multiple modes, and the battery life has been really impressive so far. Definitely a great product!

These tail lights are awful. Within two weeks, one of the two lights would drain out after 2 days when not being used. The second light worked well for about 6 weeks - maybe 15 uses. After that the power/mode button stopped working in the on position.
