I think they are always a great addition. Even If you cant use them while driving, its still cool to show the "footprint" of your ride when you touch down somewhere!! :cool
The "stigma" on them is generated from the racer kids, which suks.
But then with the "distraction" factor-
I think the SEMI's that go down the freeway with more lights than a Christmas Tree, and for no reason other than to "dress" her up are a distraction. I find myself looking at all those lights (why are there so many) and following them the whole length of the truck! - more time than I would with a quick glance at a passenger car or truck with a simple glow that provides an extra bit of road light.
Neons are a great custom addition!! :thumbs
