I am amazed at the number of mistakes I (we?) get-away-with, usually unknown
to anyone but ourselves (but for the grace of ...).
I could never forget the 'Master' because the machine had either:
1. big red panel light (homebuilt) or
2. a noisy electric gyro ("certified" aircraft)
But, how did that dome/map/panel light (wired direct to battery) rocker
switch unknowingly get bumped ON in bright daylight? Same effect as Master
left ON: dead battery. Would adding item "Check Dome Light Switch OFF" to a
shutdown checklist guarantee no repeat? Nope, because one day, some day, I
might miss the checklist item.

The pilot most likely to have an incident is the one who says it can't
happen to me!
A little fear is a wonderful thing.
This is taking on elements of the situation described in the old story
wherein NASA spent millions developing a ballpoint pen that would allow
astronauts to write while upside down, while the Russian cosmonauts simply
used pencils.
Here's a nice quick-and-dirty and cheap 2-step solution:
1. Add "Turn off Master" to checklist.
2. Follow checklist. Which you should be doing anyway.
