Hi Jeff, I guess I will have to wait until I get my clips to see exactly how it all fits together. What you say would make more sense, as that way, you can replace a headlight without having to unbolt the complete headlight/bucket assembley from inside the fender.
No problem on the later headlights. I was thinking anyway, that I don't expect to be doing much night time driving in my car, so having the later quartz bulbs wouldn't be a huge loss as far as lighting level goes. I will probably get a few spare ba20d style bulbs. Would "funky" get you a few more points at a car show??? I think putting together these headlight assemblies should be a special award category on its own!!
The Carello number on the front face of my headlight is 00.183.700. There's also some other numbers on the face - "IGM 0726 P" and "IGM 3751 LA". On the rear, there's some other numbers - "lente 00.183.700", riflettore 00.183.010" and "portalampade 50.010.751" (the portalampade number is hard to read). There's one more number on the rear - K11073 (35/35). Could 35/35 be wattage?
I have seen Selma brand headlights for sale that look the same as the Carello ones. I wonder if these are completely interchangeable?
BTW, the headlights I have now are one piece. You think there is a version to fit my style of bucket that has a separate reflector part?
Other 500/600 headlights I have seen on ebay do have the different bulb retainer on the back. They have two tabs to hold the bulb in place. Geesh, between the 500 & 600 and the different years/versions, there does seem to be quite a number of different headlights that were used. It's sure nice to have a source of this arcane/esoteric info. around! :)
Another thing, I assume that one has to be careful to get headlights for LHD cars if used in North America? Ie., don't buy them from Britain or down under?
