I don't have the van here yet but was wondering after seeing pictures of older L400s, the side marker lights always seem darker than the headlights.
Kind of odd: same manufacturer and the light enclosures are right next to each other. Aren't they made the same way? (probably a naive question)
Used that same 3M kit on our 2007 Honda Fit last night, the headlight covers on that one are (cheap?

) clear plastic, they were yellowed and cloudy.
Didn't auto manufacturers use to make the light enclosures out of glass?
I assume they use plastic because it's cheaper and lighter, as well as perhaps a planned obsolescence ploy that makes new vehicles look better than 5+ year old ones.
