Back in the pre-1980's we really felt the need for brighter lighting. I have to admit, we complained about "them dang bright halogens". Then HID came out and we complained about those too. Now we have LED's.
One of the common themes related to headlight glare seems to come down to headlight aiming AND appropriate lens. HID and LED lighting can scatter badly when retrofitted if the lens is not also changed. This, I believe, causes most of my complaints regarding HID and LED lighting. BUT, I've been blinded by new Toyotas that I'm pretty sure are stock LED lighting. Most often it's because the vehicle is on an upwards slope where it is about to level out. I'm on the level portion, so their headlights are focussed straight into my eyeballs. The regular halogen bulbs are bright, but not blindingly so.
Please, please, if you do retrofit LED, make sure you have compatible lenses.
I really do feel additional eye strain with the additional LED lighting out there. This also includes the new LED street lighting, so I'm not limiting my complaints to vehicle headlights. Personally, I have driven at least 4 types of vehicles regularly and been able to assess the function of the headlights.
My 1992 Grand Marquis, with new standard halogen bulbs had excellent lighting. I never felt like I needed more.
My 1997 and 1999 Buicks, which used the same bulb as the Grand Marquis, had terrible lighting. Maybe it was the wiring and too much voltage was lost through the wiring, but they were just awful. Getting a set of Philips Xtreme bulbs for the Buicks solved that issue completely.
My 2008 Explorer seems to have fine lighting with standard halogen. I never even feel the need to use the "fog lights". (If you need to see something that close, it's too late anyway!)
In my 2002 Tahoe, I believe I also installed the Philips Xtreme bulbs.
It's true that it doesn't light the road as much as the LED, but I really do see all I need in all weather conditions and I'm driving in Vancouver BC that has lots of poor visibility conditions. In fact, what is a more serious concern is the huge A pillars. Both my wife and I have nearly hit pedestrians because they just happened to be moving and staying in the A pillar blind spot. When it happened to me, I was consciously moving my upper body back and forth to peek around the A pillar. In the end neither of us hit anyone, be we never had any of this difficulty in any of the vehicles in the past.
I guess you could put in LEDs if you like, but make sure you upgrade everything related to LED's. Check the lens and reflector as well. Given the issue of snow building up on the LED housing, I think I'd prefer the halogens myself.
