Garmin light holder

Works with saddle bag!
Exactly what I wanted. The a ability to mount my rear radar light over my saddle bag. This allows the radar to work better, I was getting false alerts before. The bracket is study being metal, the adapter plate for light also is a robust plastic, far better the the many Ali express and Temu adaptors I have bought. Don't get me wrong, I did try to find this on both sites but only found cheaper inferior versions, which is weird as this is from China. I feel the price was expensive for a no brand make, but the quality is actually good, so overall happy. Especially as I got it next day and if fulfills my specific need of not getting in the way of my saddle bag, most others will do this! I have added pic to show how it works with the saddle bag.

Easy to fit and holds the rear light securely
This was easy to fit and holds the rear light securely. In addition, there is enough space to attach my small saddle bag under the seat.

cheap rubber band mounting doesn’t inspire confidence so purchased separate clip on type mount
works perfectly as described and sturdy but flimsy cheap rubber band mounting doesn’t inspire confidence so purchased a separate clip on type mount for sturdiness

MOUNTING GARMIN REAR LIGHT
Really good quality and easy to fit at the right position. Only those seeking something super light should be put off.

Needed a bodge to fix
This doesn’t tighten for the outer two points. Bolt tightened as far as it can but joint still loose. No internal ‘nut’ to capture on the outer side, like the saddle rails ones have. Had to bodge a repair with some nuts and bolts from my collection. Need for a ride tomorrow so didn’t have time for a return and this bodge will do for a bit… Otherwise feels really solid and metal which suggests longevity but needed this bodge to make it work…

Works well.
It does exactly what it’s supposed to do to do. Holds all Garmin products just the same or better.

Works really with my mountain bike when I want to ride on the road and need the security of my Garmin Varia. Lots of room for my dropper seat to function. Just make sure your Varia model is listed as there are two models of the bracket.

Perfecto para mí varia. La rueda me tapaba un poco el varia porque no lo podía colocar más alto. Con este agarre en el sillín es mucho más efectivo.

Much better that OEM mount and leaves room for an under-seat pouch. Very solid and east to install, light/radar goes on and off very easily.
