Looked online, bought bulbs, they're wrong.

Am I right in thinking the headlamp bulbs are:

dipped - H1
full beam - HB3
indicator - ?

 

i c no1 has bothrd 2 reply,fukn anyn eh.think they r h4,got som myself,can let u no 2moro 4 defo,as im not goin out2 the car 2nite.

 

Kin hell what does all that mean ?????

 

Just need to know the indicators now.

 

I know it's an old topic, but still google indexed this as one of the pages that holds the info.

Since there is no clarification mentioned yet, by topic resurrection let me share (2004 impreza 2.0 GX blobeye):
low beam: H1
high beam: HB3/9005
sidelight (the little one in the headlamp): 501/W5W

These are the halogen bulbs btw.
If you want to make sure, open the hood, check on the upper part of the headlight, there are 2 screws up which holds the lamp in place. If you have OEM headlight, the plastic thingy that goes from the top of the headlamp to the two screws should have the instructions on the wattage & size of bulbs. Check some videos on how to remove the headlamp for easier bulb change, they will remove 3 screws to do so, 2 from top (these are the ones that has the instructions on their plastic thingy) and one on the inner side behind the curve of the front bumper (10mm ratchets are advised).

Happy bulb-changing!
