headlights

Im looking for replacement bulbs for my car and everywhere i ask gives me a differnt answer...What is the number for headlight bulbs on a 2000 preludeSH ? Is there one bulb for high and low beam? Whats the number for the fog lights?

The headlight bulbs are H1 bulbs. There are 2 bulbs in each headlight.. 1 low, 1 high, so 4 total. Fog lights use H3C bulbs.
