Digital multimeters are useless when testing with a running engine. The RF interference from the ignition causes them to read in error.
Most analogue ( old fasioned kind with a needle)multimeters will give a good reading when close to a running engine.

Morris, if the voltage drops the current cannot increase to compensate if the resistance stays constant. Current is calculated by dividing the voltage by the resistance.

Thanks for getting that right Trev. I got a bit carried away there. The only thing that'll happen is that the bulbs will shine less bright.
I'm more used to working with electric motors.
