Review on 🚨 Enhance Visibility and Safety with the Serfas Seat Stay Taillight by Eric Krull

I have an aero seat post and couldn't find a good tail light that didn't cost too much. Most taillights I've come across have round seatpost mounts. I tried this light and attached it to a bike seat post. With durable rubber bands, this light fits any tube shape. The light is very bright and comparable to other taillights in the $20 range that I have. Some may prefer their taillight to be brighter, but I found this light bright enough during the day to get drivers' attention while not being too distracting to my passengers. I was also able to mount this light perfectly on my aero post, but I prefer it on the seatpost. Changing the batteries is easy and moving this light from bike to bike is even easier.
