H1s are specialty bulbs. Most auto stores like Autozone, Pepboys, Strauss, etc, don't carry them. If you go to a car shop, they'll charge you like $40 for a set of two nonames.
I bought 2 sets of MTECs for $35 shipped. eBay is really cheap and has good prices, just make sure that the seller you're buying from has a gaurantee and return policy.
by the way, HERE IS THE ACTUAL LIGHT SETUP:
it's stamped onto the projectors themselves.
hi beam (closest to grill) = h1
low beam (middle; halo around this one) = h1
running light (farthest to the from the grill, shares pod with turnsignal) = 7443
turn signal (farthest to the from the grill, shares pod with running light) = 168
