Ignition Switched fuse or wire in the rear back cargo area?

Here's the view out the back of my car. Notice the direct view of can't see the hood of the car behind me but in the fresnel lens I can see the headlights.

I know I'm about 18" from the car behind me when I can only see the hood and not the lights.

Works great for parallel parking.

I took pics of how I made it. Take note of the example photo with my bright red Thermo Pen in the foreground and tiny through the lens.
