Here is a rather funny installation I found several years ago. I was in South Minneapolis looking at a very nice $230k duplex. Although this property was in foreclosure, it was very well maintained with a perfectly landscaped backyard. It also had 2 garages: one double car garage for the owner that used to live downstairs and then a single car garage for the upstairs 1 bedroom apartment.
When I opened the door to the garage, I noticed it stuck slightly when it was open about 1-2 inches. I thought that was strange and realized that the light was hitting the door (not to mention the bottom of the light was at about eye level). Upon further examination, it appears the installer decided not to move the light over a little or buy a smaller light, but notching out the door was easier!
Well…I suppose it works!
