depends on how much you want to spend...

has some extremely nice HID lights but they have some salty prices...if worse comes to worse and you really want a pair i'd just try to go to autozone or something and get their best pair of super brights...but also idk if you know or not but if you have a HID kit (factory installed) on a 93 (I have a 03 also) when you start the car they auto level themselves and you will see your lights point up then down then shift back to the center...idk if that is what you want also but I dont have a clue in the world as to install that.and as for installing the lights take it to a shop and have them done...the saabs lights are enclosed and are somewhat diff. to reach for people who arent car buffs
