  Why can't just model them?
 
  It is ridiculous to see each light taken only 4 pixels when the camera
 is only
  a few meters away.

 I agree. Melchior's anticollison lights don't really hit performance at
 all. Given a property to tell them what color to be, this should be
 pretty trivial.
 

I'm not sure that the PAPI/VASI lights are the problem. The FLOLS on the
carrier does the same job and they are quite vertex intensive, but don't
pull the frame rate down noticeably.

The difference is that the runway lights are modeled using 
GL_POINT_SMOOTH instead of textured vertices.
