proper fogs wont be as good as flood for your needs as the lens should be yellow and designed for low down mounting.
We can get fogs without the yellow, though, yes, that is more traditional... I had a set of Hella 500s in a fog pattern on my old trooper. Bright, normal beam, but, more spread out than my driving lights...
I know what a "proper fog" is... but, a lot stuff is labeled either fog, or driving, with, emphasis on the spread of the light...
right or wrong, just sayin...
On that note, to the OP, beware of what you are buying... look at lighting charts, and make sure you will get what you want.
