Head Light Bulbs With more Lumens, Or as in my day... Candlepower, than OEM Head Light Bulbs, along with more brilliant White Spectrum, do tend to be Blinding... especially when not dimmed!
However, they also provide greater Braking Distance for unexpected Road Hazards at nighttime, for the Driver!
Two factors come in to play...
1) Headlight Adjustment... Low Beam should be below oncoming windshields... and I've also seen manuals that show Headlights adjusted to the right of the Center-line, so there is no direct light shining in the oncoming lane.
2) Drivers dimming their Headlights within a reasonable distance.
Personally, I try to dim as soon as I can see two distinct headlights coming toward me.
Here in Central Oregon, we have Mule Deer, Rocky Mountain Elk, and some roads with Open Range Cattle. If they aren't looking your way with their reflective eyes, they can be hard to see... especially with oncoming Headlights!
One thing I hate, is when an oncoming Driver thinks your Lights are too bright, even on low beam... as happens to me if I have a heavy load in the bed... and they put their High beam on when they get close!
Nothing is gained by two blind drivers coming at each other!
On a different note...
My 2001 Dakota had conventional Headlights, with the same "Cone of Light" horizontal and Vertical
My "New" 2008 Dakota has a noticeable cut-off above center.
My 600' Gravel Driveway has "Whoops", so the horizontal line of light separation is quite obvious.
I'm very satisfied with the 2008 OEM Headlights, so I don't plan to replace them with LED's.
I do plan on replacing my Fog Lamps with LED's... and maybe add Yellow?
Driving the 2008 home from the Dealer last Month, I had White-Out Snow, coming over the Cascade Mountains.
I couldn't get the Fog Lights to come on in the dark... Found out the next day a 2008 uses a Push on the Light Switch, where my 2001 used a Pull on the light switch!
Full-time 4WD worked Great!... My 2001 had Part-time 2WD-4WD.
