The Genuine BMW French Fogs lights
(ZKW, manufactured in Austria) are
a sporty addition to any E36 M3 or
3 series which sees lots of inclimate
weather conditions, or track use.
The yellow, or "French"
fogs as they are called, have been
shown to improve visiblity in fog,
and rain, and other poor weather conditions
improving driver control and reaction
times over white or blue hued fog
In addition, many professional track
cars can be seen running french fogs
