See my previous post and Edgy's - there is only ONE rear fog lamp on the driver's side - strange but true

I too just use the fog lights on front as DTRL. A whole lot cheaper to replace an H8 bulb than burning the bi-xenons even at reduced wattage. No need to use the bi-xenons, the fog lights work fine for me.
You can even get brighter H8 bulbs to match the bi-xenons if you want.

Are you sayin that what I see is what it's supposed to be? The drivers side rear fog light is the only one of the 2 that brightens. How did you come to the conclusion there was only one rear, I'm curious ,( i'm not questioning you) PS lmao If you only knew how long I spent tryin to fix a problem that never existed. Thanks Jhbrennan

We covered this in brief once before, for the USA market (and Germany, and many others) only one rear fog light is supplied. The UK market employs two. I believe the logic behind the 1 vice 2 question comes down to keeping tail gaters in thick fog from confusing a set of two bright rear lights (brakes!) from a single bright light (rear fog). Years ago when traveling up for an early flight out of Amsterdam I was particularly happy to see so many people had rear fogs on their cars! It really helps.
Recently I got pulled over in California by a very courteous CHP who told me that I had a light out. I quickly realized that I had accidently selected the rear fog on detent,--and turned it off, satisfying his curiousity. (I think he was curious about the odd plates and the odd car, as well; I'm still awaiting my Calif plates and have left the tourist del. plates on).

Anyway, I don't use them. I just use the fogs for now. I do not use the rear single fog unless it's, well, foggy.

In any event, the fog lamps are enough for DTRL in my opinion.
One day, I have to change these to the new Xenon match H8's just to brighten them up a bit more.

Deanski: I got the 'match H8's. There's no wattage change - he justs adjusts the color spectrum to better color-match the Bi-xenon main lamps - only comparable when both are on. Amp up the wattage; you're likely to melt something. ..done that already on another car.
...got the clear/yellows for the sides too.. but the best ones were the little license plate lamps. They really change color to a nice blue/white. $12.
Mason: Like others have said - it's only the LH. My Canadian Mercedes (better exchange rates) has the same thing. Canadians also require DLRs and I can't imaging driving any color but Yellow without. ...it just my wife doesn't pay attention to the difference between one pull and two. Like, cruise control, Mercs handle this function better also. Porsche needs an 'intuitive' advisor.
