And some states limit the number of lights that can be lit at once - Virginia
for example limits it to 4 lights. If both low and high beams were on, you
couldn't add fog lights, driving lights, etc., let alone the running lights on
the front.
But it also might have something to do with fuel economy. Lows and highs
together would draw a bit more electrical power, which would mean that the
alternator would have to work a bit harder, which means a bit more load on the
engine, which means a tiny bit less fuel economy. By itself, not a bit deal,
but add in the requirements for CAFI, and every little .1 mile per gallon adds
up bit time. Who knows?
