Better check what the manufacturer states. If it's got a medium base, convention dictates that the screw part is negative and the button is positive. I sure don't like using AC fixtures for DC circuits or appliances....

So if your alternator is putting out 14.4 volts, you won't fry your 12-volt LED fixture. If you're retrofitting raw LEDs into an existing fixture, then yes, they are definitely polarity-sensitive. Read the instructions that came with the LEDs or fixture -- it should tell you.
