I did not see a ballast anywhere or any extra wires running over to the battery so it might be safe to assume they are an H1 bulb.
I guess my next question would be: how do you remove/install these bulbs? It doesn't look like the typical setup where you twist a plastic ring and pull the bulb out. From what I can see, there appears to be a rubber boot that can be pulled back and then there is a metal clip of some sort which might be what holds the bulb in place...not sure though. It looks like a bitch to replace even the low beam bulb. If it was the left side that was bad, the battery would have to be removed to get at anything!
Got it. Ok then removal is easy.
First there are 2 slide pins located underhood that secure the entire assembly in place. Remove both and you can then pull straight out on the housing. Pull slowly and behind you'll find your main harness plug. Disconnect that and next you'll have to see how the extra lights are wired in.
If you have quick disconnects then disconnect both the positive and negative wires and you should be able to pull the housing completely out.
After that you can get a better look at how the bulbs are secured. First pull back that rubber boot, there is a slide on electrical connector that slides onto the bulb itself, disconnect that. After that, you'll find a small clip that needs to pushed in and then to the side and out, its a retention clip. Once its loose you'll see the bulb which can be removed now. H1 bulbs have these small round tabs that guide the bulb into the correct position, they can be a pain sometimes to get in properly.
