I understand the blinding concerns, but with a lot of cars (including my own) it's not a factor. Very rarely do I see foglights on a car that affect my eyesight more than just headlights -- it's always the tall trucks and SUVs that really cause a problem. Then again, tall trucks/SUVs and brand-new cars all blind me anyway, fog lights or no (I can't even stand waiting at stoplights behind some of the super-bright brakelights on new cars), so there still isn't much of a difference.
+1. From personal observation, I think the vast majority of fog light applications on cars made in the last 15 years simply do not blind oncoming drivers as Army Chief says.
I think this may actually be a manufactures' response to their misuse. Years ago when I started driving, fog lights seemed to be aimed higher than they are today. The fogs on my E30 really could blind oncoming drivers, so I left them off unless I needed them.
But these days, they don't bother me at all. People around here drive with them on all the time; I don't even notice them.
What I can't stand is the lazy fools who use their daytime running lights at night --on early cars, DRLs use a lower wattage bulb in the highbeam lens. But they can still dazzle you like highbeams because they are aimed at your face instead of the ground.
Of course, here in Jersey I see someone driving around at night with no lights at all at least twice a week.
Speaking of misuse of lights, let me relate an experience from a few weeks ago. My neighborhood is wooded. We live at the top of a small mountain and there is a wildlife reserve not far from my house. We have MANY deer in our area.
One night on the way home up the mountain, a deer jumped out of the woods about 60-70 feet ahead of me. I stopped without a problem, but once it cross my side of the road, an oncoming driver had a close call with it. But he/she was able to stop in time.
Now most people around here know if you see one deer, there are usually more. So we all stay put for a few seconds and I start scanning the tree line of both sides looking for more.
Then the other driver switched on their highbeams. It was a large SUV with very new and effective bixenon HIDs.. a Lexus LX or something along those lines. Regardless, they were ****ing BRIGHT.
And I'm sitting there thinking to myself, "gee, I'm glad you can see well enough to look around for Bambi's mom, but now me and everyone behind me can't see a damn thing. Thanks ********!" The amazing thing is that even after I flicked my own highbeams a few times at this person, they didn't bother lowering their lights. They drove all the way down the mountain with them on... blinding the **** out of every one coming the other way.
I fumed about that selfish idiot for the rest of the night. Ask my wife.
