Yup.  The old myth about amber light (especially monochromatic sodium light) 
penetrating fog better is just that - a myth.  The filters just cut out 2/3rds 
of the light.
The important thing about fog lights is to place them as far away from the 
driver's vision axis.  The idea is not to have the fog that's lit up by the 
outbound beam in the driver's field of view.  That's why sharp cutoffs are 
good, and why the lows should be _off_.

Clear.  Sounds a good combination.

Agree with all that.  Also keep the lenses _clean_.  Dirty lenses increase 
dazzle with high-powered bulbs.
