First let me say up front that I am old. 53 in fact. I don't get the whole bake your headlights in the oven fad!?!? Never heard of it til now. Does it darken them or what? And....why do you want dark lenses reducing your vision at night? Where I live the deer are thick as phiuck! I've hit one on a bike and one last fall in my car. Not to mention coyotes, drunken idiots and other creatures. Don't get me wrong. I have no problem with anyone doing whatever they want to their vehicle. I don't get it and there is no need that I do get it. Please enlighten me on this oven baking thing you speak of
