With headlights on, no you won't. They aren't like the pre-2004 Impreza that had huge, significant fog lights. If you turn off your headlights, though, and the roads aren't crappy and it's not raining (or... foggy) then you'll see what I mean.
People will definitely see you, though, which is all that really matters for those things. I would like to look into the reverse fog light for the BRZ.
