Am surprised to hear all fords are not the same.
Depends who designed them. You’ve got ford doing it themselves, one of the companies ford owns/owned doing it or a supplier to ford doing it. All three giving different results depending on how they’ve interpreted the requirements. And how loudly the project leader has shouted at them (which is directly related to how recently they had to change a bulb on their own car)
I think it is more to do with style over function.
But they’d look ugly.
Nah, the front end crash rules are pretty strict. Both internal and legislative. You have to pick 2 out of 3, lights that work, front end that meets or exceeds NCAP5 or easy to change the bulbs. IIRC the headlamps are (generally) the hardest bit of the front of the car, as they have to stay exactly where they are and not wobble, bounce or move. Everything else is generally speaking, crushable, moveable or a skin over a lump of padding.
Actually it’s more like pick 8 out of 13 than 2 out of 3. But the principle is sound.
I just take our car to the workshop to get new bulbs, mainly as they are about 100 quid each and need recalibrating if you muck it up. (got fancy pants bendy bi-xenon lights)
