Well, I just replaced both my turn signal bulbs.

Remove front bumper = 15-20 minutes, didn't disconnect foglights, disconnected the PDC harness.

Remove PS pump bolts, headlights pushed forward, didn't disconnect anything, R&R turn signal bulbs = 20-25 minutes

Replace bumper = 15-20 minutes.

So, about one hour without rushing. Easily could do it in less time.

I'm not sure why it took me so long to replace the bulbs though. All I know is its pretty crazy to have to remove the bumper and headlights just to replace the turn signal bulbs.
