9003's. There are several numbers that have to do with which bulb is correct for whichever application your intent is. They may/may not work in yours. Seems like I recall that Hella's use H4 bulbs. Those you showed are H2B's. I got this info from reading the numbers on the metal base of the bulbs, so I didn't make this data up. My Tundra uses 9006's.
