2002 BMW 540I Exterior Lighting Problems

THE PLASTIC COVERS ON THE HEADLIGHTS OF MY BMW BECAME CRAZED/FROSTED. EVERY BMW OF THIS VINTAGE HAS THE SAME PROBLEM. I SHOWED THIS TO OCCUR IN 2010 AT 100,000 MILES, BUT IN FACT IT WAS A STEADY DEGRADATION OVER SEVERAL YEARS. IT'S A SAFETY ISSUE, BECAUSE THE LIGHT OUTPUT IS SIGNIFICANTLY REDUCED.
