I think most rear fender liners would work.
I have a set of never installed American adventure labs rears with the logo red match for a rubi I’ve never installed. They may be up in the marketplace.
It doesn’t work like the factory bsm but still is functional. I found it to be ok. But I did put mine back to stock I ended up likening the factory look. The backup lights are sensational!
My old set is for sale in the marketplace.
