you guys whining about DRL's need to take your head's out of your butts. the fact that they piss you off is an indication that they are doing their job, which is making sure you notice the vehicle. they are not bright enough to have the slightest impact on your vision during the day and they are DIMMER than the real lights on a car, so what's the big deal?
conjor, those links are ridiculous. DRL's don't cause glare for me, and i wear big-time-glare glasses (i can often see my own eyeball reflecting in them). maybe these people need to get their eyes examined. not only that, i have to laugh at the "argument" that once all cars have DRL's that they will cease to be effective because people will be used to them. right, so because we're "used" to cars being brighter and easier to see, we'll stop seeing them? what the hell? i don't magically not see school buses because they're all painted bright yellow so that we can see them. i don't magically not see motorcycles because they have their lights on.
the only problem i can see from them is that sometimes people forget to turn on their real lights (don't they ever look at their instrument clusters and notice that they can't see their gauges?). that and that they make your car more noticeable to the cops (again, simply because they are doing their job).
