Check the actual headlight unit. Toyota likes to stamp things on the unit. It should have on the top the type of bulb it uses. From guess of what Japanese like to use, the highbeam would most likely be H3... low beam could be either H1 or H3 (more likely H3 for the projectors). But I am 99.9% sure that it's not H4 or H7.
Parkers does jack all, so I wouldn't worry about that unless you want to change the colours of the parkers (legal colours are stock white, yellow and orange).
