I’m not sure what you mean by headlight doors. Those look like Euro headlights which have completely different buckets. Available as OE Bosch or Hella for $$$ or aftermarket such as by Depo or TYC for about $200. Depo brand fit and perform well enough. TYC fit poorly. Used OE come around for about $200.
