Certainly they are operated directly by a computer, ie without the use of a relay. However the computer still has to have enough power to run and the LEDS have to operate on a nominal 12V (up to 15v?) so can't be expected to also run on very low voltages. Also as I understand it, the battery registered 7+ volts after having been disconnected, ie with the high current load removed and therefore expected to have been at a voltage lower than 7 volts and falling!
Perhaps hazards need to operate from a separate battery like the alarm system, or even run from the alarm battery so they always work even if there's a dire electrical fault elsewhere. Mine will be converted to run from my aux battery.
