Proper foglights have a pattern that is about an inch high (exaggerating)
and approaching 90 degrees wide.  They are meant to be mounted as low as
possible, ideally almost touching the road, to give grazing illumination
that is well below the driver's line of sight.  Trust me, the do the job
beautifully when your low beams are just throwing a blinding white cloud in
your face.  You get to drive at 15 mph instead of 0.  But that's all
they're really good for.  They do fill in the sides of a poor low-beam
pattern, but only in a very narrow vertical band.  If bad low-beams is the
problem, the auxiliary low-beam installation (hella?) is the ticket, with
fog lights a poor second.
