That'll be tough but if you really want you can get some true HID/xenon retrofit kits for the foglights. Otherwise, it's probably going to be a Hoen product or a PIAA bulb of some kind. I don't know exactly what Dave's AE's look like and what colour you have but I'll assume you're talking about white AE's.

Hey, you're in HK so you should be able to find all kinds of bulbs. I was down in that area where all those little car accesories shops are and they had all kinds of stuff.
