Keith - @$#%$@!
Hey I'm glad you are happy with yours - you may actually be the only one with a Porsche 928 DRL active...? - where are all the Canucks when you need them! (insane diegans probably don't count...)
I didn't expect everyone to think it a good idea... but at least you like the DRL.
- Sterling - just get the same relay Keith has!
I don't think I want a new dashboard light either - But since I'm leaning to having the markers included - that would naturally illuminate the exisiting "marker only" light on the dashboard - the one that warns you your markers are on but your headlights aren't (in soothing green).
I won't be doing anything for a while - but there are a few good ideas kicked out here already that have influenced my thinking.

Yea, my opinion tends to differ from a lot of folks. 
I have had the DRL for over 6 months now...never had any unwanted attention. (and I AIN'T drivin' like Grandma!) From what I can tell around LA, NOT having DRL puts you in the minority. To each his own, so the option of turning them off is attractive.
I suspect that it would be rather simple to install the DRL relay and just "switch" it somewhere OR just by-pass the circuit that does not allow power to the fogs from the main circuit headlight/marker wiring. I may go for something like that if it were out there.
I know on our runs to some of these events, DRL's are almost a must. Folks just fall asleep at the wheel in the "show-off lane". Before I had the relay, I used to just run with my parking lights on and the fogs. No good...can't see any of them in the day 'cept for the fogs. Then when you actually hit the brakes, there is less contrasting red to wake up the person behind you. I say this from experience and comments from others. The relay was a gift, but in hindsight, a very good one and I love them.
If you're asking though, a photocell activated headlight system with a 1 second delay would make for some nice high end convenience. It would just save my precious time while driving from having to reach over 6" 's to twist the headlight switch.
Needless to speak of how my passengers would be so impressed!

Keith,
What was the part number of the relay please?
IIRC there was a VW alternative - maybe the same but cheaper.
I'm with you on the safty issue. "See and be Seen".
Alan,
I mentioned the dash light because it is on both the van and the bug.
Don't need it personally.
Thanks,
Roger

Sean,
Buy a 90+ and you can do it easily with a (hard to find) plug & play relay...
Otherwise you have to rewire - it is possible to do and actually quite easy - the 30 terminal on the Fog light switch in the pod normally comes from the 58 terminal on the main light switch (for "1" mode). It can just be swapped directly to an ignition (15) or accessory (X) supply (doesn't really matter it will work exactly the same for either). Then the fogs will come on whenever the fog switch is on and switch is in accessory or ignition positions - but will be disabled during starting. On a US model the fogs will still go off with high beams.
This works for an '88+ haven't checked all models but I believe its similar for all...

ROG right you are, there are several things that a VW dealer will have rather than paying Porsche 928 prices! I'm not a safety freak but in my opinion, this relay is worth it.
I checked and couldn't pull the bugger out as those realys are in the panel so tight. I used a mechanics mirror and read it backwards so I hope I got it right. Relay p/n is 100 951 0001 ...located at III on the fuse panel.

Alan, how about wiring the fog light switch to be able to be on with the headlight switch on 0 (0-1-2 like you said) and the ignition on. Then wire a relay to turn on the markers with the fogs.
Bill Swift, there are plenty of statistics out there that prove that daytime running lights are a huge safety improvement. I'm amazed it took Americans so long to catch on to the idea. Well, no, I'm not. American car companies are not interested in safety and neither are lawmakers.

Nearly all published reports indicate DRLs reduce multiple-vehicle daytime crashes. Evidence about DRL effects on crashes comes from studies conducted in Scandinavia, Canada, and the United States. A study examining the effect of Norway's DRL law from 1980 to 1990 found a 10 percent decline in daytime multiple-vehicle crashes.1 A Danish study reported a 7 percent reduction in DRL-relevant crashes in the first 15 months after DRL use was required and a 37 percent decline in left-turn crashes.2 In a second study covering 2 years and 9 months of Denmark's law, there was a 6 percent reduction in daytime multiple-vehicle crashes and a 34 percent reduction in left-turn crashes.3 A 1994 Transport Canada study comparing 1990 model year vehicles with DRLs to 1989 vehicles without them found that DRLs reduced relevant daytime multiple-vehicle crashes by 11 percent.4
In the United States, a 1985 Institute study determined that commercial fleet passenger vehicles modified to operate with DRLs were involved in 7 percent fewer daytime multiple-vehicle crashes than similar vehicles without DRLs.5 A small-scale fleet study conducted in the 1960s found an 18 percent lower daytime multiple-vehicle crash rate for DRL-equipped vehicles.6 Multiple-vehicle daytime crashes account for about half of all police-reported crashes in the United States. A 2002 Institute study reported a 3 percent decline in daytime multiple-vehicle crash risk in nine U.S. states concurrent with the introduction of DRLs.7 Federal researchers, using data collected nationwide, concluded that there was a 5 percent decline in daytime, two-vehicle, opposite-direction crashes and a 12 percent decline in fatal crashes with pedestrians and bicyclists.8

Matt,
I understand that most of the saftey stats for DRL's are from Scandinavia where there is a prolonged twilight due to their latitude. Canada also.
In USA DRL's advantage is increased visibilty to our aging population, but still we don't have the 17 hour days with 4 hour sunsets as up north (for the summer).

Matt,
- Its actually easier than that.
Do what I already said => Swap the fog light switches 30 terminal for an accessory (X) input then move that disconnected wire (to the Light Switches 58 terminal) to now be fed by the fog light relay output (terminal 87) via a high current diode.
Then when you turn the fog switch on and the ignition is on the markers will come on with the fog lights.

Dave McK, the second paragraph is all about the US. It's not just far northern countries and twilight.
Alan, I'll have to remember to look back at this thread once I get my CE panel repaired. The fog lights are what burned up the panel...
