ISO 100/200, F7.1, shutter speed to get correct exposure.
Not to disagree with you (there's nothing wrong with what you said), but settings can vary quite a bit more than that. Of the two long exposure light-trail shots I have in the database, both were 8 seconds, but one was F14 at ISO100, and the other was F9
I think what Eric is looking for is light-trail photos (though I'm not sure). If so, shutter speed may be a primary consideration.
For me, with the two aforementioned light-trail photos, I stopped down the aperture to "tame" the bright lights into looking like something other than blobs, and to have a large depth-of-field. Shutter speed was set to capture the light-trail I wanted. ISO was then selected to achieve a correct exposure.
But really, the only way to figure it out is to get out there and experiment!
