another newbie question ... H2 or H4 bulbs ??

I noticed alot of people talked about gettin the H4 or 9003 bulbs for the headlight. I was checking my owners manual and noticed that it states that H2 is the correct size.


Anyone have any idea whats the difference and whats the correct size ?? i have a 02 Si.



Thanks


and in regards to my last post bout the apc 3d euros, thanks for all the input and i am definitely not gettin them.

me too

H4 is the type of buld for our car, DO NOT USE any other H series. H4 is the type of connection. FYI

The H4 bulb is exactly the same as 9003 and HB2 not H2

after pulling out my oem headlight bulb it is indeed a 9003 or h4. then why in the hell would they print hb2 in the manual ??


thanks for all the replies

Like CivicSiR4U2NV said, H4 is the same as HB2 so the manual didn't print anything wrong. It is also called 9003.
