Review on 🚲 Cygolite Hotrod – 90 Lumen Bike Tail Light with 6 Night & Daytime Modes – Wide Glowing LEDs – Compact & Sleek Design – IP64 Water Resistant – Sturdy Flexible Mount – USB Rechargeable – Ideal for Busy Roads by Chris Russell

I chose the Cygolite Hotrod 50 bike tail light because the reviews said it was aero strut compatible. I'm happy to report that this light fits my Pinarello Prince Aero seatpost with no problem. It also fits seatstays, however quite a bit of elastic is left on one side. This light is so bright I almost cum when I turn it on. Pro tip: Don't look at it when you turn it on, as it will turn on in daylight. I recommend this product because it's light, fits well, and easy to use. Press a button to switch between modes, which are listed in order in the instructions (get it, someone got it), and hold a button to turn them off. If I had to pick one thing I don't like it would be that the battery life could be longer, but that's it. The charging port is on the back, so it needs to be removed. In return, however, you protect the connector from the elements by being on the back of the light.
