{Roy Smith asks why cars don't have headlight relays}
#1 reason: cuz they is CHEEP!
If you put a relay that switches that much current in a car, it
may cost several dollars per car. Multiply that by 100,000's of
cars, and .........
#2 reason: We don't need to.. (see #1)
But on most European cars, you must have a parking light
displayed on the road side only, and it must turn off when the
car starts. As part of this wiring, you end off turning off the
headlights.
BTW, did you ever notice that import cars ALWAYS have separate
brake and turn signals? You cannot license a car in most EC
countries without same. As a consequence, the 4 way flashers
work, even when your foot is on the brakes.....
