2003 Toyota Corolla S Lighting...

I got a few questions...
I m new to this forum and I just got my girlfriend a 2003 Corolla S.
I wanna change the headlights and fog lights to PIAA Xtreme White lights.
I was told that I need 9006 for the head lights but nobody knows what I need for the foglights...not even the dealerships.
So if anyone knows, can u please let me know if i need an H3 bulb or H4 and how much wattage...
also, a lady from toyota said that if i do replace them then the whole thing can burn and its costs A LOT of money...but if i get the right wattage then nothing can happen, right?
has anyone had problems with PIAA before?
please lemme know, thanks a lot.

Go look at your owner's manual for headlight bulb size.

she wasn't given an owner's manual, they didnt have any with them...i know, pretty fcked up...

take the bulb out, and match it at the store when you buy them. :)

PIAA's are the best quality bulbs.. The most common model for foglights is usually H3 but you should try and take it out and find out what shape it is.. That's the safest way you can go..

If you look carefully at the lens, many times the bulb size will be displayed. A neat little thing Japanese car manufacturers do.

PIAA's are the best quality bulbs..
No they arent, they're just the most overrated bulbs out there... Try some Philips bulbs, damn I threw my PIAA's in the lake after swapping in the philips ones...
