New to the world of 964(lovin it ), so I will probably be posting some daft questions so please bare with me!
Need new headlight lenses and my current ones have H7 on them(93 C4) but when looking I can only seem to find Bosch lettered with H4 on them, could someone please tell me what the difference is and can I just put the H4's on?
Any help would be appreciated _________________ ___________________________

The simplest answer is that H4 are combined dip and main beam in one bulb, H7 are single filament bulbs, one each for dip and main. _________________ Mike

Thanks Mike, so I take it the lenses have a different pattern on them due to bulb positions and I can't just swop over the lenses to H4 style?
And I also can't put H4 bulbs in as the wiring/socket will be different in my H7 headlights. _________________ ___________________________

Just remembered the lights have been changed to HID's and have a dual beam bulb so now I'm thinking H4 lenses would be right
My head hurts now _________________ ___________________________

The bulbs are not interchangeable, their bases are different sizes and, of course, the H4 has an extra terminal (the flat blades) 3 rather than 2.
However, I'm not familiar with 964 light (mines a 996). You may find the lenses are the same. _________________ Mike

The glass on all 64's are H4 but they come in RHD and LHD forms.
