Just to share a recent inexpensive repair, my wife's 01 Max SE's headlights were severely hazed over from UV/Sun that they appeared yellowish. I bought on of those 3M headlight restorer kits (autozone $20 or Harbor Freight $10) and it worked like a charm, the headlight lenses look brand new and she indicated to me that her ability to see better at night greatly improved. Not actually a gimmick.
