While driving my 25 year old truck at night, I have difficulty seeing when there are other vehicles' headlights facing me, or behind me. The situation is the worst when they are newer LED headlights. When they are behind me, I can see my own shadow reflected inside the cab from their beams. Facing me, the lights are blinding, and it's hard to see the road. I was ready to chalk this up to fading vision, but then the other night it was so bad that I tried an experiment.
I drove into a steady stream of traffic with my incandescent headlights switched to high beams. I did this for an hour, and that whole time I never had an oncoming driver blip his lights at me. That seemed odd. In the old days, if your high beams were in someone's vision, they were quick to let you know. My theory is that the brighter LED lights have upped the ante, so that my high beams are no longer blinding to an oncoming driver, because everyone else's lights are so much brighter. I think everybody's pupils are contracting because of the brighter light, and as a consequence, brighter lights are needed in order to see.
Has anyone had experience upgrading older, sealed beam headlamps. I hate the blinding bluish light from LED's, but I like being able to see where I'm going.
