Lightcord on the Inside or Outside?

The right way to rig your canister light is with the lightcord on the outside. Another way to express is it is to have the switch on the inside. The reason for this is when the light is on (as it should be for most of the dive), you want the switch to be pointing backwards. Your right side backup light can sometimes bump the switch boot backwards; you want it to bump the switch in the "on" position. The first picture below is the correct orientation of the lightcord.
