Turn the power off to the circuit first at your Breaker/Fuse panel. Once you know that the circuit is dead, remove the old fixture One of the 2 wires goes on the black, the other on the white. If there's a bare ground, ground that to the junction box where the fixture is going.
Secure the fixture in place with the provided hardware, and turn the power back on at the breaker/fuse panel. If you did something wrong the breaker will trip/fuse will blow.
Didn't strain my neck during installation because I positioned and stuck the panel to the dome light housing, while the housing was removed from my car, and was on my workbench, and I was looking down at it, instead of looking up at the housing, while it was in the car. A 2010 Toyota Matrix dome light. The housing comes out of the ceiling very easily, by squeezing 2 clips, diagonally opposite each other at the corners of the housing.
If you center the 1.5 by 5 inch panel in the space that is available for it, one clip will be completely obscured.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
