200 fog lights and bulbs

[e2e]

Hi all from the four-ringed circus.
One of my fog lights is broken, Audi quoted too much and couldn't get one
for ages. What brand is this light and a part number please. What other cars
have them so I can comb the bone yards?
I have also just replaced a headlight lens and want to upgrade my bulbs,
standard are 60/55w. I see that you can get xenon +30% and +50% in 60/55w or
bigger wattage coventionals. The high wattage bulbs come with a warning not
to use them in polycarbonate reflectors, but then the spotlights are already
100w and part of the same cluster, so more grunt shouldn't be a problem or
am I wrong. But which bulbs are best small bright ones or just plain big
ones?
Oh these are euro lights by the way.
