Hello, my name is Mark Clapp and I make plexiglass headlight covers for XKE series 1 cars. The plastic I use is shatter proof. You can fold it flat back onto itself and it does not crack so rocks/track debris are no problem. These are perfect to reduce weight for race cars or just to eliminate the trim ring look. I'd like to offer the light covers for $80/pair shipping included. Feel free to call me at: 816-767-3924 (days) or 816-525-8851 (home). My email address is: info (at) cleverapple (dot) com. I can also make other pieces as needed.
