Fortunately, both the Indians and the Taiwanese make much better replacement/upgrade lights. Here's some samples of their work as installed on my cars:
87 Jaguar XJ6 Vanden Plas/TWR replica
90 Nissan Pathfinder (beater)
Somewhat subtle, but the clear-lensed (as opposed to fluted or patterned) headlights make a huge difference in light output. And they're properly sealed.
I thought he was talking about the lens specifically. I may have missed whether this was one of the integrated designs.
