oh and btw you neglected to post the next paragraph
"One problem with this conclusion as drawn from the French experiencewith selective-yellow headlamps in France is that when the questionwas being considered, the lamps that were being compared with whitelamps reduced the absolute intensity of the beam by about 12 percent.This fact may have had a part in reducing the glare. Because therequirement for yellow light no longer exists (though such light is optional in many countries) we probably will never know the vagaries of the answer to this question"
not picking a fight, but why do something to your car that provides no benefit to you or those around you, and invites tickets?
