Regarding dazzling/blinding.... only time I've had to pull over and stop was on a small rural road. Turned out it was a tractor, well off the road in a paddock with a giggawatt spotlight pointed down the road.
Well the choice of the algebraic notation was not mine, but the equation still stands. The first link from LMGTFY is this -
