HI!

 I WILL LIKE TO KNOW WHICH OF THESE HEADLIGHTS IS ROUNDER.  I KNOW THAT ONE HAS A FLATER FRONT GLASS SURFACE THAN THE OTHER.  IS IT H5, THAT HAS THE ROUNDER GLASS SURFACE?  THANK YOU AGAIN EVERY ONE.

DON'T SHOUT!!

My '86 has H4s, the '90 GT has H5s. There is little visible difference. The H5s have three aiming nibs on the face, the H4s don't. The best clue is that the H4s have a big "H4" in the center of each lens! There is no visible difference in the flatness of the lens.
