I think the fog light interlock stems from old school headlights and the 4 light rule.
But it makes absolutely no sense as OE "fog lights" which are typically called driving lights anyway are the least offensive to oncoming traffic and they typically do a good job complemeting the high beams. Which should be shut off anyway with oncoming traffic.
Over the years I have done some mods to lighting on vehicles. And in my world, Fog lights and Driving lights are not the same. My last Pete, I had a pair of each mounted and used. The Driving lights, only able to be on with high beams, would light a area well past and to the side of the high beams. The fog lights, would not come on with high beams. And if I was out in the country in heavy fog, I would shut headlights off. The amber worked best.
On of my Super Duties, had a 4 lamp headlight system. Loaded to gross, aim the headlights to where I could see down the road on High beam, when MT, would shine up in the trees. Replaced the inner pair with double filament like the outside. Added a 2nd headlight switch/relay and another dimmer switch. Mt, used the factory set. Loaded, put factory switch on park for taillights, turn on other switch for low beam inside pair. High beam on that switch would light all 8 filaments.
Roadside safety inspection, CMV inspector said the wrong headlights where on. Showed him how it worked. "Not sure that is legal, but good idea." Still got a overload ticket. Changed so the outside worked when loaded. Preferred to be stopped MT.
You're 100% correct scooby and the discussion has turned to the light cops talking about OE "driving" lights which aren't offensive in the least to oncoming traffic.
I've got real driving lights on vehicles too. The kind that let you see a deer in the ditch 300yds away (or 250m for Jaxdad) those are not acceptable to use into oncoming traffic. But they're also useless in the greater Toronto area. Not where I live and drive though.
