Defective headlight lenses in July 2006, a 1-inch diameter opaque "discoloration " appeared in left front headlamp lens, directly in front of area closest to halogen bulb. Besides impairing light output, I was fearful that defective area would eventually break or crack, allowing water to contact halogen bulb - causing it to explode when hot. (2005 Toyota Highlander was 18-months old at that time, with 25,263 miles. ) Toyota replaced same under warranty. Now same lens defect / discoloration is occurring to right front headlamp plastic lens at 45,000 miles, and again fearful that lens failure will result in exploding halogen bulb. Unsure it Toyota will cover this second repair. Headlamps and bulbs are original factory equipment.
