Yes they were some beat headlights. The answer is simple the 2007 Suburban is mine I live in Arizona, sun is hard on everything. I have had to replace dashboards, headlights and the rear spoiler because of sun damage and my truck is garage kept. But I love my truck it now has a 173 thousand miles. I am sure it will be the subject of more videos.

 

Interesting... Sun here isn't too bad, of course our cars are parked inside at home and at work, so they are outside very little I guess.

in PA we have road salt in the winter that will eat through a car in a week with rust destroying wheels, brakes, body panels, and the frame!

 

I don't believe the head lamps need to be removed to replace the bulbs, but as I understand it, its still a chore...
