I don't think the polycarbonate used for plastic headlight fronts has changed that significantly.Michel wrote: ↑19 Jun 2018, 08:12white exec wrote: ↑19 Jun 2018, 06:51Plastic headlights do not survive exposure to bright sunlight - 000 000's of cars here with yellowed and matted lights, impossible to completely polish out.
I agree this is an issue on cars with older plastic headlights, but I've not seen it being an issue with post 2010 cars.
Quite possible that "post 2010" cars just haven't been exposed to UV for long enough for the irrevocable damage to take place; it takes a few years for this to begin to show up.
But are we really saying that headlights (at up to €500 a throw, if with sealed fronts) should be replaced after this time? Perhaps we are.
OK, northern Europe doesn't get the intense and virtually daily high UV levels we do here (Mediterranean), but it can't be too much to expect cars to survive something as predictable as sun in Spain, can it?
