Sidelights are meant to be used at "lighting up time", or, when you are parked and it's foggy.
When I asked my driving instructor (last week) about when to use sidelights, he said "What's the proper name for them?". I said "Parking lights..?", to which he replied "Yep, hint is in the name."
He said to use those when parked on a dark country road or on a road where the speed is over 30MPH, and headlights when it starts getting dark. He said not to drive with sidelights because they're not really bright enough to matter.

It's horrible isn't it? I have driven in fog where I was literaly struggling to see much further than the end of the bonnet, and the reflected light from dipped beams just makes it worse.
My Fogs are god damn useless as they are on most cars with modern projector lamps and xenon lamps.
What annoys me about my car is that, I cannot just have the rear fogs on, you have to have them both on, which is stupid, in 12 years of driving, ive never needed to use the front fogs, the rear yes, but not the front.We just dont get the fog like that anymore.
