Figured you guys would appreciate this.

I didn’t want to buy a new rack that accommodated a rear light. I had been searching and searching for brackets that would retrofit. I was finally able to find one.

My main issue with a camera and light under the saddle is when I used the rack for anything other than panniers, both would get blocked. I used the under-saddle camera mount to sandwich onto the plate and long screws and washers to affix the light mount.

Now I can use my rack!
