No - they have a transformer to get to 12 volts. (or at least some do)
One thing to beware of is that house stuff may not be voltage regulated so if batteries are charging then the voltage can be higher and blow the leds whereas automotive and boat kit is normally regulated
My vehicle had halogen fittings for all the lights which ate power so i got led bulbs for them and converted them over. All my lighting switched on now uses less than the power of 1 halogen
