For 65 Dart there are amber lenses and clear lenses only. If I'm correct the FPC shows clear for export only. All 65 Dart exported to Sweden had clear lenses. Even today clear lenses is the only option here.
That's all correct. When I had my '65 (Canadian Valiant Custom 200; the tan/beige one here) I wanted a set of the colourless lenses, but the only vendor who claimed to have them was Layson, who was (and still is) on my "never buy from this guy" list for a long list of good reasons.
I have a question for you. The dome light has a bulb with 2 prongs!
That is true. It's because this is a 2-wire lamp (feed and ground) rather than a body-grounded lamp. The door switches and the dome light contact in the headlamp switch complete a ground path for the dome light, which has constant +12v feed. This is much easier and safer than providing a constant ground (by using a single-pin bulb with body ground), because that way would require a fuse for each door switch, a fuse for the contact in the headlamp switch, and would have a lot more "hot" wires running up and down and all around within the body.
On the lamp under the dash board is also a lamp with 2 prongs.
For the same reason. I don't have a spec for the bulb type in the courtesy lamp under the dash -- might be a #90, which is a 75-lumen bulb with a G6 globe. The dome light takes a #1004, which is a 189-lumen bulb with a B6 (bigger than G6) globe.
