My sonata is just over 5 years old and it's still my baby. I have washed it once a week since the day I bought it. It's driving me crazy seeing the headlights turn brown from sun damage. I recently bought a house so I am now parking in a garage but have been out in the sun for the past 4 years. The solid white bars on the tops of the headlights are so exposed to the sun so now those white bars are brown. Before dropping $1,000 on new headlights, does anyone have any remedies or products they recommend for headlight discoloration? I've tried some of the basic ones and no luck.
