Bulb type for oem foglights on first gen aveo

i am just wondering what the bulb type is for the oem fog lights on a first generation aveo. i want to get those nice yellow bulbs from a local store but i dont know which bulbs fit. i think that the oem headlights are H4 and the aftermarket projectors are H1 but i have no idea what the foglights are .. :( any help would be great :)

ps.

its a pontiac wave but i think it has the exact same bulbs as the aveo

I believe if i still remember correctly from doing research for HID fogs, the bulb number is 891. I still havent had money to buy the hids because the pulley was more important at the time lol
