Usage of daytime xenons or DRL?

Driving around with your fogs on for visibility or as an alternate to DRL's is just plain wrong. Fog lights are for foggy conditions with limited visibility, if its clear, fogs should not be used.

Isn't that interesting.
I guess I've never seen much written on the subject....probably missed it.
The current headlamp system is pretty incredible....anytime someone rides in my wife's cab they're amazed at how the forward illumination is 'tuned' to illuminate almost nothing higher than 3' or so.
For someone who has never seen it before.....it's wierd.

I am familiar w/the DTRL strip......and also the strip when full headlamps are engaged.
You sure that either of those actually qualify as "fogs"?
I just assumed the engineering of the beam-angle on the current headlamps was so incredible....traditional "fogs" were deemed unnecesary.....but what do I know.

The LED's are just broad spread defensive lighting, they are not designed to illuminate anything for the driver of the car to see, but for others to see the car. There are LED illumination systems designed to replace other headlights, but they are tightly grouped LEDs and include focusing systems such as parabolic mirror surfaces and lenses.
Agreed, there is a fog tail light on the 997.2. And that does work in the traditional fog mode, that is, its is very bright and also, should not be engaged unless there is thick fog/rain/snow (with visibility of under about 50m in Germany, misuse gets you a 40€ fine and 1 point on your record).
The point of that is its as bright as a brake light, and if its on it confuses following drivers about whether you have your brakes on and one bake light out, or not... it becomes much more likely that drives behind you will not notice when you do step on the brakes, if you've been driving the whole time with your rear-fog on.

Has anyone driven one of the new Audis with LED headlights?
As far as I know they are the only ones doing headlights.
LED are great for being seen , but for actually illuminating , I think they are still a work in progres

$7K R8 option.......for that they better do more than just look cute.
And the 918 Spyder's interesting lamp array....must be LED or Flux Capacitors in there.

Those LED running lights are in the location where older models had fog lights installed, but those are NOT fog lamps. Fog lamps, like headlights, would have a much more significant light output (equivalent to a low beam strength of illumination) and be focused. A quick test will confirm that. Drive at night in a dark neighborhood street with your 'DRL's on.. and see if you can see the road surface out to 50+ yards in front of your car at a brightness equal to headlight illumination. Fog lights provide that, but from a lighting position lower on the car's front end, to cut under the fog and provide less bounce-back reflection, thus obscuring your visibility rather than helping.
