Well those of you that run in snow or dust might disagree with the yellow
light theory, what yellow light does is give depth in low visability
conditions,tho it does give about 15% less light vs a clear........   There
are many ProRally guys that might disagree with the dumb statement, in fact
this one believes the exact opposite......  A good Hella Z beam or eurobeam
headlights is nothing more than a clear fog light, what you gain with clear
lens fogs is the sharp top cutoff, but so do most "euro" style lights......
 So putting the fogs on in clear, if you have the euros already is
redumbdant.......   You are better off having the ambers to "mellow the
effect" of those 100w bulbs you put in the Ralleye 2000's, and/or to give
depth to the "pure" white and highly reflective light from a hologen
bulb........

Hmmm, not sure I agree with the summation, here

Not sure Hella or Cibie/Marshall would agree with you here, they make yellow/
and clear fog lenses for just about all housing apps.....  And believe me,
they aren't cheap.......

A litttle off on that one, not sure that the distance from the top of the
bumper to the bottom of the bumper on lense centers is significant to the
human eye

  Thanks to our brain-dead politicians that specified a

>favorite car, the Lotus Europa, but don't get me started on that.  Many

Interlocked to the low beams is the law in most states fogs are to be mounted
a minimum of a foot from the ground.....
Now you must differentiate between a fog and a driving/fog here.......  There
are only a handful of cars that come with true FOG lights from the
factory....  There are millions of cars that come with "sport lites" as I
call them, or commonly are H3 driving/fogs......   these are the Dumb lites
you might/should be referring to...  A light is either a driving a pencil or
a fog, and can effectively be only one of the three........  And the blame
should go to the car manufacturers more than the politicians, if the
manufacturers put proper fogs and aiming procedures were followed on cars the
politicians would need to get involved as much as they have........

>Detroit made a bad design decision with vertically-stacked quad 
headlights.  They elected to put the low beam light on the top.  On my 
Dad's Suburban in a snowstorm, the light comes right back in your face.  
I have swapped the lights, putting the low beam on the bottom, and now 
see much better in snow or fog (don't have fog lights on it).  It is 
interesting how many of my buddies have noticed something odd about the 
>truck, but they can't figure what it is...   
Detroit and the US have the worst headlight systems I've ever experienced,
the US spec q's are no different........


Better lights are more carefully made and have more defined patterns.  I 
liked Cibie and Hella in the old days,<<<<  Hella are the only ones left here
in the states, but Cibie/Marshall is still very much alive cross the pone
>>>>>>>>>>> but I really don't have any idea 
who makes the best ones now.  You want ease of mounting under the bumper, 
ease of aiming, a good flat-top beam, clear lens, lots of power<<<<<  Fogs
should be no more than 55w BTW
>>>>>>>>>>
.  Mount 'em low, aim them carefully, and you will see well and not blind
oncoming 
cars on a flat road (breaking over hills is a problem with oncoming cars 
no matter how high lights are mounted.).
 <<<<<  Mount them solidly as you can, as in very, no shake at all, strut
braces and no shake will make up for a couple inches of vertical placement


Done a few, clearly
and a few amber waves......
