One of the links regarding headlamp alignment was this: http://www.danielsternlighting.com/tech/aim/aim.html

In this article, one needs to identify the headlamp type in order to place marks on a wall that are the targets. My question is, do our US cars have "US DOT headlamps marked VOL or do we have S DOT headlamps marked VOR, and mechanical aim low or high/lowbeam lamps?" This is taken from page 3 of the PDF version of this informative "how-to"

I have looked on the glass cover and the headlamp enclosure..... anyone know?
