if you look at the road in front of a xenon-equipped car, you will see WHITE.
(i know if you look at the light source it looks blueish)
the road in front of a halogen will look positively yellow in comparison.
btw i think the mid 80's pontiac 6000STE had plastic headlight lenses.
maybe other GM's of that vintage also used them?
