parking light question

I personally prefer the way chrysler did it. I like how much contrast there is between the lamp being completely dark and then suddenly being on. I feel that it is too hard to see the front turn signals on many modern cars because of the lack of contrast combined with headlamp intensity. On the old stuff there was no question it was dark and then (kinda) bright. I am not positive but I recall reading that the lighting legislation for front running lights with headlamps was 1967 US model year cars, but I could be wrong.
