Fog Lights as daytime driving lights (DRL)

'07 XK 42. NA engine.
So, I upgraded the corner markers to W5W LED's. Didn't work: too dim to be used as practical DRL's.
Then, I upgraded the foglights to H11 LED's, and manually turn them on. The fogs make good DRL's for daytime use. Never use them at night, so not concerned about brightness.
My question is on SDD. I can reprogram for DRL usage, but want to use only the foglights as DRL. Activated DRL's on SDD, but only came up with the headlight lowbeams. Anyone know of a SDD setting that'll automtically use the fogs as DRL's?
Thanks!

I purchased a set of the combo DLR's & fog lights from Adamesh several years ago. Installation was "medium" as I had to remove the tires, fender wheel well covers, and get underneath the front skid plate for mounting, wire runs, etc. IIRC, it only took a couple of hours to do and they've performed flawlessly since.

SDD does provide for DLR when you toggle the option, but not on the fogs. You could do some rewiring and achieve this without much ado.
A question though... why do you want fogs as DLR anyway? I see dozens of people who drive around at night with just the DLR and no tail lights because they see light in front of them and don't turn on the headlights. It's a real problem where I am. If it were up to ME, I'd mandate that DLRs also include the Tail Lights. Such a hazard, these things.

I only use DRL's during the day, and the fogs because(a) the markers are too dim, and (b) the xenon lowbeams are too much -- and with Hella lightpods being sometimes subject to heat-related wire rot, I don't want to use them unless needed here in Florida. It's easy to switch the fogs on for daytime use. Further, replacing the yellow halogen H11's with white LEDs doesn't matter for daytime use.
As to taillight use -- the original reason for DRL's here was research that visible front light sharply reduced accidents. Insurance company's likely pushed it. Not sure if visible daylight taillights would do the same.
So I suppose manually switching on the fog DRL isn't much of a problem. Lazy me....
Thanks, LoudHog for the great idea on combo fogs/DRL's.

That is interesting. Are DRL compulsory for new vehicles in the USA? I ask because, for many years now they have been mandatory in the UK and I can't recall the last time I saw the situation you describe. It is certainly not common. So what I am wondering is this: if the DRLs are mandatory, and have been for some time, it makes a difference as to how drivers interact with them? Here in the UK we seem to have just 'gotten used to them' and they don't have a bearing on how we use our main lights at night.

Maybe you just don't notice because they are going the other way?

lol, what baffles me @Cee Jay n aren’t the lights in the instrument panel not activated until the lights are turned on?? so we both have too many people driving about with no rear lights and no intention of looking at the instrument panel??!!

People over here and lazy and cheap. They don't purchase (or maybe don't use) auto-on headlights. They instead waddle their way out of Walmart, get in their car and drive away. If they see any light from in front of their car, they don't even bother thinking "Turn On the Headlights" and go for miles with a faint glow emanating from the front. Of course, no tail lights anywhere. Every time I make the fifty mile drive home from my daughter's house, I see at least four incidents of this. While driving around town at night for half an hour, I see at least two.
