Out of alignment - is that "up/down" or "in/out"? Either way, try this:
There are 4 phillip screws that hold the entire front, including the shelf. One screw at knee level on the driver side, one on the passenger side, and 2 at the bottom front, down by the carpet, in front of the gear shift.
Loosen all four screws. Pull the shelf out far enough to make sure there are no wires (grounds, lighter, etc)in there that got pinched between metal and plastic when you replaced the bulb and reinstalled the shelf. That could throw off alignment. Make sure there's no carpet bunched up near the 2 screws at the bottom that could throw off alingment. Check each side, as the inside 'kick-panels' are also held by the side screws. With everything lined up, hold the shelf level in place. Make sure it's where you want it, then tighten the screws on the sides. Then tighten the 2 screws at the bottom. Good luck.
