Bulb difference

[toyotacelicagt4]

Hi,

I'm looking at changing the headlight bulbs on my 1996 celica and was a little confused on what bulbs i need. Some websites say i need h4 bulbs and others say i need hb4's?

Whats the difference between h4 & hb4? And does anyone know which ones I need?

Thanks
ps its just the dipped beam bulbs i need

Hi,

Best way of being sure is to take them out and have a look.

H4 Bulbs look like this

HB4's look like this:

Going from the powerbulbs website it says you need HB4's.
