I'm right there with you! Lack of high beam discipline is paramount on my list of things that other drivers do that anoy me.
Thank you for not taking that as some sort of sideways insult or attack. I seriously doubt you would blatantly create a hazard without a care.
I am also interested to find out if people start flashing you. If that happens, I'd be interested to watch as you try to do something to alleviate the problem other than just getting rid of the bulbs. (Aim lower. Put tape or paint over the top 1/4 of the headlight. Etc...)
Point is, I too would like to see down the road better. And while I am interested in whether there is anything practical and cheap that can be done to retain as much of the advantage as possible, while reducing the hazard to others... I am too cheap to buy some of those bulbs and do the experimenting, myself.
I think this could end up being pretty valuable 'customizing' information for the whole community.
And it looks like you'll get your chance to experiment soon enough, with how quickly the day is getting so much shorter.
