Don't know if this point was made before, so apologies if I'm repeating here...
Having been stopped by police in a road block for using fog lights, I was told that you need the letter only if you are using the lights. If your fog lights are off, then you are safe. If your fog lights are on... AND... you get stopped by the police, only then will you need the letter to show that you have permission to use them.
In short, you don't need special permission to have fog lights on your car.... but you do need special permission (i.e. the aforementioned letter) to turn them on.
