Headlights

I have an 89 BMW 325is, it had the ellipsoid headlights, but someone backed into my car so I had to buy some new headlights, I bought them off of http://www.importvision.com, they're H1s, but that's not the problem, they have a strange two tower plug in the back of the bulb it looks kind of like ( o o ). I can't find a plug to fit, and NAPA doesn't know what kind of plug it is. Also, one of the plug covers on the back will come off so that you can change the bulb, but the other won't move (can't remember which one moves, they're not right in front of me). If anyone has these headlights, or have any ideas, please help, as of right now I only have one head light, and it's pissing me off. They're DEPO lights, so thanks again for any help.
