There has been discussion of why FMC has chosen not to incorporate actual fog light assemblies on the 6th Gen's....
They've probably figured out that the vast majority of people who want fog lights almost exclusively intend to use them as "bling"—AKA an extra factory-provided place to display (but not actually use) an HID
bulb. Those that don't have the resources to do an HID
swap just decide to keep the factory fog lights on anyway for that little bit of extra "look at me" factor, even though the skys are clear and visibility is slightly worse than unlimited.
At the same time, the number of people who want fog lights for the absurd purpose of seeing in the fog seems much more limited these days, perhaps due to ignorance. "Oh, I didn't know I could turn my fog lights on in fog so I can see better!"
strips accomplishes the hot marketing goals of "bling" and "look at me" factor much more cheaply (and arguably more effectively) than an actual headlight housing that must be designed to hold a bulb and to aim the light in a specific pattern just so the driver can see better in some insignificant ground cloud condition.
Meanwhile, to make up for the loss the engineers are busy working on a long-range collision avoidance and vehicle guidance system that works in adverse visibility conditions such as dense fog
! "For $2000 buyers are getting a great value with enhanced safety."
Just wait, in ten years actual working fog lights will be the next big thing in automotive marketing! "Wow, now I can actually see what I'm about to hit in the fog before I hit it! Before I only got an alert about it, this is way cooler!"
Corporate-driven technological progress is great isn't it?
