are the low and high beam the same bulb size from the 94-97/98-01?

for example i want to get a 98 front, and i have hid's... will i need to get another hid bulb for the 98 headlamp? im currently a 94, or are the same.. i looked on team integra and their sayin they are the same.
but i tried sellin a friend of mine a pair of hid's that i had from a previous integra and they didnt fit.... can anyone confirm?( he was a 98-01)
