    Step 8 says to remove the nut behind the light in the upper cave - is that step necessary? I removed the plastic skid plate type thing and it was easy to access the bolt and nuts mentioned in step seven without having to take the tires off....

    I believe you are correct. Step 8 is not required. When I did this, it was my first time and it "looked" like that nut was holding the headlight assy in.

    Those light are led they can't be change . If they are off that mean that the wires are bad. But if you only want to change it because you don't like they color they plastic on the head light that orange not the bulb. If they are not working also check the white parking light on the front. Is also off it may be a harness problem it is very easy to check. There is a plug between the fuse box and the coolant tank. Unplug that with a tester test the plug . My car had a issued with the right side it was not comming on. The right side wire color for it is purple. The left is different we had to jump it from the plug to the light to make it work. Good lk.

    Or...for the Parking light/DRL bulbs...(the ones the OP changed)...you could do what I just did in <30 minutes....just reach down beside the headlight, take the one T20 torx screw that holds that little white plastic funnel looking thing in place (it only serves to be a guide for the technician's adjuster tool to hit the right spot), remove the little plastic thing, grip the socket, gently twist it and pull it out. Pull out old bulb, push in new bulb, stick the socket back in place and gently twist it in the opposite direction to lock it in. Put the white plastic thing back on with the one T20 torx screw, test your work, then put the black cover back on. Done!
    NOTE....if you have large wrists and large stubby fingers, you won't be able to do this...I'm a pianist with skinny wrists and long fingers.

    Is this the same process used to replace the front turn signal bulbs?

    Thanks phigment. I just answered my own question.

    It definitely is. I upgraded my turn signals to LEDs and had to go through the same process. I'm just glad I've never had to replace the headlights.

    No such thing as HID parking lights. The bulbs are 194's.

    I swapped the 194's out for LEDs. That is why they are bright. If that is something you are looking at doing, I would strongly recommend purchasing quality LEDs. The cheap ones will not last long enough to make it worth your while.
