So in short, fog lights are not permitted to be used as DRL...
I don't think that is or at least was strictly true in some jurisdictions. So for example, a '90 928 has the option of activating the fog lights as DRLs through the addition of a relay, which is something the factory did in Canada for example. I assume Porsche was in compliance at the time...
Is there a particular reason to care whether Porsche was allowed to do it that way and sell it as a new car? As long as it's done in such a way that oncoming traffic is not blinded, I think there is very little chance of law enforcement taking an interest.
That's been my experience here, in VA- I have driven through Charlottesville at night a few times and on the highway as well with just the fogs on, no problems.
Here is a pic of just the position light by itself. I just went to a better bulb here... down to 960 lumens from 1200... and with an IC driver too so it can stay on for very long times. The position light lens does not focus the light, it is designed to be seen from everywhere so it scatters it.
The previous too-bright bulb meant it flared up in fog. Our new position light bulb is better, and has a projector lens on the end to help keep the light down...
In fact, Daytime Running Lights or DRL's are not supposed to assist the driver by illuminating the world at daytime, but are meant to make sure others see the car during daytime. The official DRL's shine light in "every" direction to the front. There is a lot of legislation about DRL's: https://en.wikipedia.org/wiki/Automotive_lighting
It says: Passenger cars and small delivery vans first type approved to UN Regulation 48 on or after 7 February 2011 must be equipped with DRLs; large vehicles (trucks and buses) type approved since August 2012 must be so equipped.[28][28][29][30][31] Functional piggybacking, such as operating the headlamps or front turn signals or fog lamps as DRLs, is not permitted;[32] the EU Directive requires functionally specific daytime running lamps compliant with UN Regulation 87 and mounted to the vehicle in accord with UN Regulation 48.[33]
Prior to the DRL mandate, countries requiring daytime lights permitted low beam headlamps to provide that function. National regulations in Canada, Sweden, Norway, Slovenia, Finland, Iceland, and Denmark require hardwired automatic DRL systems of varying specification. DRLs are permitted in many countries where they are not required, but prohibited in other countries not requiring them.[25]
Front, side, and rear position lamps are permitted, required or forbidden to illuminate in combination with daytime running lamps, depending on the jurisdiction and the DRL implementation. Likewise, according to jurisdictional regulations, DRLs mounted within a certain distance of turn signals are permitted or required to extinguish or dim down to parking lamp intensity individually when the adjacent turn signal is operating.[7][18]
So in short, fog lights are not permitted to be used as DRL. Positionig lights will not comply with DRL legislation. In countries were DRL's are required by law (not in the Netherlands), positioning lights will not be allowed to be used as DRL's. In countries where DRL's are not required, you can use the positioning lights any time you like, also during daytime. So in these situations where DRL's are not required by law, the positioning lights can be used as surrogate DRL's. That is what I intend to do. I have a special electric circuit ready that will switch on the DRL when contact is on and headlamps are off. With your LED's in place the positioning lights will be more effective as DRL. This will make the extra DRL's I have ready to be installed under the bumper redundend. This is good.

In Canada, fog lights (all my Audis used them) or the turn signal lights (the bright element. My Chrysler minivans used these) are legal as DRL's
Just ordered a set of fog and position lights for my '83, let's see how they are! I already have LED H4 headlights using Ed Scherer's cap system (https://rennlist.com/forums/928-foru...id-or-led.html) and want the same color temp for the foglights and position lights as with the headlights, otherwise it looks all wrong.
I hope the color matches. No doubt it will be closer than the current halogen-to-LED comparison you have now. Our Fogs and position lights are 5500 degree Kelvin to match our LED headlights. Do you know the color of your headlights?

The point was where DRL's are required (primarily in Europe) - The USA does not require them which is why USA cars were not so equipped. Canada seems to allow fogs for DRL and those were so equipped.
Fog Lights - yellow LED replacement bulb recommendations?
1980 928
I'm looking for recommendations on "yellow" LED bulbs to replace the stock OEM white halogen bulbs. I want these to be bright / high lumen yellow
I'm open to purchasing the yellow Euro lense but would rather just pop in yellow colored LED bulbs.
I want to avoid an assembly upgrade.
And I want to be sure anything i do doesn't trigger a warning light or fry or complicate anything in anyway.
Any suggestions / advice / heads up much appreciated.

. They put out 1800 lumens per bulb which is a bit more than the standard 50watt halogen bulb (1350 lumens). These bulbs do fit in the scockets of the fog and driving assembly and they come in white or yellow. You will need to split the rubber sleeve covering the leads to ge them to connect to the OEM loations.
Thanks Michael & Alan.
Michael - can you send a pic if its not too much trouble?
Also what do you gentlemen think of going the extra distance and purchasing the yellow Euro lense?
I'm not a purist for my 1980 928 so i want to have some fun with it within a reasonable budget.
And i dont want to make any mistakes with parts that don't fit or are complicated to install so i'm taking on some layup projects and replacing the tired looking white hallogen fog lights with yellow fog lights seem to be one. Please correct me if i'm wrong.
Just saying, but not all Euro's came with yellow fog lights.
Only the French came with both fog lights/parking lights and high beams in yellow. Spanish market cars had only yellow fogs/parking lights but clear high beams, and most other European cars had all clear lenses.
The ones you show in your picture are not fog lights but the high beams (these were only yellow in France). Next to those are the parking light/fog combination, yellow in France and Spain (and most outer lenses are orange indicators).
My 928 has all three colors, orange, yellow and clear.
