Standing lights?

I have been told by other drivers when I use the rear fog lamp that one of my tail lights are out.
I don't have much use for either light option.
The law states that the side of the car which faces traffic has to be lit. There is even a road sign (#394), which is mounted on public street lighting poles that shows that this light is not on all night. Therefore you have to use your "parking light".
.....hardly anybody knows anymore....
