Plexiglas is acrylic, not PC. Another brand I've seen locally is Acrylan.Plexiglass is polycarbonate, but not necessarily the other way around (plexiglass is a trade name)
You've heard of Lexan?...that's polycarbonate. Lexan is stronger...better for bulletproof windows...but both types of plastic are easily scratched and extremely vulnerable to chemicals and UV.
As for the comment that the TY aftermarket units have slightly lower quality component parts, it is hard to imagine a shabbier design and build than the OEM headlights on my '97.
