fog laws

[William Murin <murinw@cs.uwp.edu>]

Forgive me for coming-in in the middle but obviously there have been some 
changes in federal and/or state laws in recent years.

My '87 4kcsq has dealer installed fogs.  when I obught the car in '87 
service department wired them in to the low beam circuit even though I 
wanted them wired in to the parking light switch.  tehir response:  its 
the law--cannot run fogs without the lows on--and of course they go off 
when I switch to my "bright" lights.

My wife's '90 Olds came factory equipped with fogs which I can run 
independent of the low beams.  Switch on the parking lights and then 
switch on the fogs.  Presto, fogs without low beams.

Dont know when the laws were changed.  Probably came after the change 
which allowed us to move from "sealed beams" to headlights with 
replacement bulbs.

Probably some federal DOT regulation will explain it all.  If I get a 
chance in the new few days (& if I rem,ember) I'll search the Code of 
Federal REgulations on the internet and see what I can find.
