## Customer Reviews

### ⭐⭐⭐⭐⭐ Best light accessory
*by S***6 on November 30, 2023*

This mount should come by default with lights. It attaches securely beneath the saddle, and I have no worries about it falling off. I also like that it lets the light be horizontal to give a bit more visibility than a vertical mount.

### ⭐⭐⭐⭐⭐ Works for what I wanted
*by J***N on May 12, 2022*

Ordered to attach a rear bike light, works great

### ⭐ Didn't fit.
*by A***R on October 22, 2024*

Seemed good enough on quality, but the notches didn't fit the saddle rails.
