Why does an incandescent light bulb have an broad, continuous spectra when viewed with a spectrometer? Why doesn't it have some lines like a sodium lamp? I guess I'm asking why photons come off of a black body and why are their wavelengths spread out. Bonus points for clarity and accessibility of the answers.

Apropos of nothing, why would the wiring going to the fog lights on a US 2002 VW New Beetle have an extra unattached plug on it? This is not the lowest model, but came with the fog lights standard.

On second look, it occurs only on the drivers side wiring, the passenger side looks normal. Please stop me from agonizing over this superfluous detail!
