    I have a 2005 Ion with a sick turn signal. One of the two filaments
    burned out. Saturn conveniently made the replacement operation
    tool-free. Replaced the bulb and it still doesn't blink.

    Checked the bulb and in-headlamp assembly wiring with an ohmmeter and
    by hooking it up to a 12 volt supply. That leaves the control

    I've heard of this happening on 2003's and 2004's. Anybody run into
    this on a 2005?

    And last, the bulb has 2 filaments, one higher wattage than the other.
    Which way is it supposed to go in? The bulb is symmetrical with no
    polarity markings.

    Check underhood fuse block.
    Hopefully you didnt backfeed into the BCM.
    Not related.
    Polarity does not matter to a light bulb. One filament is for the
    hazard/parking lights, the other is for the turn signal. If you still
    have problems check all of your bulbs.

    Will do, thanks!
    I did the checks after taking the assembly into the house. It's dark
    and cold at night. Have to say, I like how they mount the lamp
    assembly. There's nothing like no-tool installation.
    The phrase polarity wasn't quite right; there aren't + and - terminals
    on a bulb. However, plug it in one way and the parking light gets the
    brighter filament. Take it out, rotate 180 and plug back in, the
    parking light gets the dimmer filament. This seems like an
    application begging for a key/tab/asymmetric layout.

    The center connection should be the ground, one outer one is for parking
    lights, the other outer is for the turn indicator. The brighter one is
    the turn signal of course. Yeah there should of been an asymmetrical tab
    so it can only be inserted one way if one filament is brighter. Keep in
    mind you can use your hazard lights to help see if any bulbs are burned
