I had an extra LED landscape light that a neighbor had given me.
Bought this 2 pack of small thin plastic orange cones for a $1.
All I did, was to drill a hole in the top of the cone and then place the solar LED on top.
I drilled the hole just the right size so as the solar LED fits snugly on top of the cone.
Illuminates really well and will be a good device to be located near a tripping hazard.
