Why...

... are the tail lights on new cars as bright as the headlights on old cars?

Sure, I understand the value of LED's - they last longer - but come on! That raw light blasting into my eyes at a traffic light is burning-out my retinas. Put some sort of refracting or diffusing lens over those things to lessen the blow. There should be a set limit on lumens (the light equivalent of decibels) on both headlights and tail lights. The car companies are manufacturing these things with way too much brightness, and I'm not surprised if it's contributing to accidents.

(Sound of me stepping off soap-box, applause.)
