The only headlights I try paying attention to are the Camaro, Yukons, Mustangs, Impala'*, Intrepids, & Crown Vic. Especially the ones that have the red & blue bulbs shining ever so bright.

I know what you mean. I know the Crown Vic headlights like the back of my hand.

The easiest cars to figure out by the lights (besides Bonnes front and back) are mid-late 90s Saturns, Integras...often with aftermarket fogs, Tauruses, Intrepids...

i would say the Taurus but if you see their red & blue lights its already to late. Cuz all the ones I saw the lights were on the flip down visor.
