This site listed my 164 as having H1s, however, Halfrauds listed it as H4, so I ordered H4s. I haven't changed them as the light in question seems to have a relay missing from the jobber on top of the light housing.

I guess my question is threefold; does my car (97 3.0 Super) need H1s rather than the H4 and do I need a relay and where can I get it?

My 93 164 Super has four H1 lamps. Used for both main and dip beam. My relays are already in the wiring loom - you shouldn't need anything else.

The Super fog lamps are H4.

Just saw something on the Alfa BB site that the early 164s had H4s in the headlamps

You don't have a bunch of wires and a relay sitting on the back of the lights? Another difference, I guess!

No wonder they work so much better than the ones on my TSpark!

No I don't and this makes me wonder what you have. You mean actually connected to the back of the light units - not the relays on brackets fixed immediately above the lights (with the black plastic covers)? Sorry to ask a "numpty" type question here.

Yeah, those are the ones I mean. I'd have to remove them from their stands to get to the lights, but they don't seem to be actually connected to the lights.

Yes, that's right. Nothing to do with the headlights - it's just where they live. One of them on the passenger side is the hooter relay I think.

I also have a diagnostic connector there hanging on the same bracket - unfortunately I don't know what bit it diagnoses. In fact I can't identify or locate any of the other diagnostic sockets (nor find anything that can read them).
