    I'm rewiring the lights on an older Fisher which the previous owner installed a set of aftermarket lights on (basically look like the older traditional Fisher style).

    Behind the orange-colored lens are two bulbs--the lower has one filament and the upper has two. How should these be wired? I'm guessing that both bulbs should be on when the parking lights are on (on my older Dodge, that means whenever the headlights are on), and the second filament in the upper bulb is the turn signal/hazard flasher.

    Is that correct, or is it the other way around?

    You might want to check to make sure that the single filament bulb is the right one, usually both bulbs were dual filaments. And yes your right, one is marker and the other is turn, just make sure that you get the turn on the side that is the brightest when powered up.

    The lower bulb has a socket with a single terminal, so I presume it's designed for a single filament bulb.

    I looked at some diagrams from Fisher, which unfortunately don't show the wiring schematic in detail, but it appears that with the newer Fisher stuff anyway the brown wire is for parking--so in my case that would mean the reverse of what I guessed--the flashers activate both bulbs, the parking lights activate one filament in the upper bulb alone.

    Can anyone please confirm this?

    That sounds right , brown is parking , other colors for directionals.

    Yes you are correct. I have a set of lights on my Hiniker that are setup like that. The upper bulb (2 filaments) is both parking and turn signal, and the lower bulb (1 filament) is just turn signal.
