H1 may be the bulbs used in those projector headlights. Popular retrofit projectors these days are the TSX projectors, S2000 projectors, and hybrid TFX(Infiniti FX projector with a clear lens swap from TSX or others). They use those and put them in stock headlights. Any other projector built for HID will do also, like the BMWs, Lexus, Mercedes, and Audi. These projectors use D2S bulbs. Again, I recommend you looking in the lighting section for further information. There is loads of information and even a tutorial for the retrofit. Here is a complete guide on the process
