LED's are cheap - try another one in the same configuration, and if it blows, you know it's a wiring problem.

Also, I'm not sure, but is the resistor supposed to be on the anode leg, or the cathode leg?

If you soldered it to the longer leg of the LED, that's Anode, and it's the input side... I was under the impression that the resistor should be on the Cathode side, but I don't know why.

EDIT: Doesn't matter what side it's on, so ignore that question. Are you certain your LED's are rated for 12V? You might try limiting the current to them even more than the 10k resistor...
