Thanks for all the help. Once I deduced that h4 was a generic type of bulb instead of a Hella-specific part, I was able to call Autozone and get a Sylvania substitute. What a difference! Worth every penny of the $500. The car now looks just like it should. It is obvious that these were the lamps designed to go on the car. Can't wait for it to get dark to see how much better they light the road.
