The LEDs may not use much of any power but the inverter has to use power just to boost the voltage no matter what the load is. How much, I don't know but it's just one more component to crap out on you when driving at night. I always carry an extra incandescent bulb when driving at night. I never had any problems seeing down the road with standard bulbs. I don't drive it much at night though so it's not much of a worry anymore.
