15 month update. I ended up going with the headlight kit from Walt501’s guy over on the ford truck forum. He sent me new focused-beam housings, new HID bulbs, wiring, etc. The result is bright light with a sharp cut off when using low beam. Lights up the whole world on high beam. I think I paid the guy $425-ish for the DIY kit. I’m a happy camper. I don’t know the guy but I would highly recommend his system. Here’s his email:

Anyway, thanks for all the helpful campfire replies, as usual.
