Headlight aim too low?
Has anybody noticed this before? Is it just my two? Am I nuts?
Thanks for listening.
Happy Holidays!

Also, a lot can happen in 10 years. The headlights will usually burn out about every two or three years, so in ten years, it probably gets replaced at least twice. With the old sealed beam lights, the aim will be significantly affected when you replace them, and most people don't bother to check the aim afterward. I saw one of the flush mounted lights with a crack in its plastic housing, which made it impossible to hold a setting.
Headlight performance is an obsession with me, so I always try to make sure that my lights are adjusted properly. I also made changes to the stock lights for better illumination. If you have the old sealed beam lights, you can make very cost effective improvements by switching to something like Sylvania's Extra Vision lights, or spend a little more and get a set of European spec E-code lights. If you have flush mounted housings, you're stuck with the optics they provide. You can still isnstall the Extra Vision bulbs for more light. In either case, you should install relays in your headlight circuit to switch the lights, as their low beams use higher power than stock to produce more light, and the stock wiring and switch will overheat.
Oh yes, avoid those stupid blue painted bulbs, no matter who makes them.
I could adjust the passenger headlight with no trouble, but the driver's side had a broken adjustment screw mounting nut. It appeared to be good and I could adjust the headlight within specs, but the first bump I hit and the headlight would shift down. This nut is just a plastic nut similar to those used on the license plates that snaps into a squared hole. The plastic nut had split and when sitting still could be tightened, but any bump would cause the headlight springs to pull the adjusting screw through the nut thus changing the alignment. I replaced this with an oversized plastic nut from my junk box and adjusted it just fine. It has worked fine for the last two years.
On the possibility of the headlights being off, you have to remember that they have probably been replaced at least once or twice over a 10 year period and not everyone knows which screws to loosen to remove the old burnt out lights. It would be easy for someone to loosen the adjusting screw and forget to realign the headlights after replacement.
