I designed this LED wall mount for the kids room and the stairs. 

It will hold the cheap LED lights with a stick diameter of 18mm wich one you get for a dollar at Walmart for example. If your outside LED is from the diameter bigger just scale the design to your need. 

I used this ones here:

You can mount them with double sided tape or with two screws on the wall. Holes for screws are on the back.

Printed in PLA, 0.12mm and laying on the wall side. No support or raft was needed for my KE.
