Bicycle Taillight by Geared2U - Extremely Bright 9 Led 3 Function Rear Bike Light - 2 AAA Batteries Included - Fast & Easy to Install - Stay Safe and Keep Your Loved Ones Safe

Disappointed in the clamp that attaches it which doesn't fit properly.

Super bright light, way brighter than anything else I've tried, (especially in this price range). It must have a very low power draw as well because I use eneloop rechargable batteries and get at least 20-25 hrs on mode 2 flash. Very easy to install to seat post but I have a lay back post and wanted the light to be horizontal and mount to back of seat so I modified the bracket slightly. Also, Excellent customer service should you need them.

Too often I bike with something that precludes a seat post mounted light being visible. So, I modified the light case by cutting a slot behind the mounting rail (with a hack saw), and securing it to the back of my bike helmet. I looped a zip tie between two holes on the back of the helmet, and slipped the modified clip behind it. It is easy to install and remove, and is always visible. I think the future of biker visibility gear is in the direction of these ultra bright lights for daytime use. I bet the Geared2u product engineers could improve on my gerry-rigged helmet mounted rear light.

Poorly made light. Do not buy this. The on/off/toggle button doesn't work well and you have to press multiple times to turn on or toggle off. Furthermore, when riding with these lights, any bump causes the light to lose its position and snap to a horizontal position pointing down

Pros: It's bright and battery life is good. Cons: It broke and the mount lacks versatility. As you can see below, one of the little plastic tabs that holds the red cover on broke off and now the cover won't stay on. That happened when I hit a bump in the road and the cover came flying off. This has happened to me with other lights before, but never enough to break the light. The other main problem with this light is the mount. It only attaches to the seatpost. That wouldn't be so bad, but when you take the light out of the mounting bracket there is no way to clip it on to a bag or a belt or anything. Most lights have a little belt clip, but this one doesn't.

Mount not very flexible.

I have purchased many rear bicycle tail lights in the past years, but this one tops them all. Even during daylight use the 9 LED output is "Extremely Bright", compared to others at the same price point. I really like the "All Lights Flashing" mode because to me, it increases the attention of the approaching motorist behind you. If your looking for a "Extremely Bright" rear bicycle tail light, I would highly recommend the purchase of the G2U - C007 tail lamp by Geared2U.

Meets expectations. Good price.
