[s-cars] Qu: Headlight alignment

[Tony]

Have been messing around with headlights (e-code lenses) and was wandering what is the "ideal" location of the bubble for the alignment. Is it with the middle thick black line passing thru the centre of the bubble? Or, should the bubble be located between the centre back line and the line closest to the lense?

Bentley only describes using the Beamsetter tool.
