P60 Dropin Adapter for Halcyon Scout Backup light

Small adapter to use a P60 LED Dropin (KDLITKER P6-L2 Cree XM-L2 800 Lumens 3V-9V LED P60 Drop-in, ~9$US) in my Halcyon Scout 3C Backup Light.

I had to remove the small inner spring from the dropin.

An additional spacer as an electric connection between the batteries and the dropin and an O ring to hold the spacer are required. I didn't find an appropriate spacer so I cut one out of an old copper plate.

There are 2 tubes acting as a battery adapter. With the outer tube I can use 2x 2170
