You mean they don’t come with instructions or a video?
I dont have a set, infact im waiting for answers to my questions, but I think thee installation can be summed up as:
1. Remove the mirror farings. They are designed to pop off when bumped into (mirror strikes). They are held in place with 3 male/female spring metal sockets. Just pop them on the mirror side with the palm of your hand, or pull them away from the bike. There should be a plastic keeper that prevents them from falling to the ground.
2. There’s a mounting bolt (see pic below) below the mirror. Use that as oriented in the picture (which is in the OP).
3. Attach your light module/pod and wire it up, and test it. Repeat for other side.
4. Replace the mirror farings.
