One upgrade/replacement I need to add here although I've mentioned it elsewhere.
I recently changed out the headlight bulbs for LED bulbs. I originally was only going to do the low beams, but there was such a vast difference in color I decided to do both. It was a vast improvement in the light output and doesn't seem to impact cutoff with no bleed over. The highs no longer dim as DRLs but since it is daylight it doesn't really impact anyone (I checked it myself from another car). I just have to remember to turn on the low beams when its starts getting dark, but I'm pretty good at that. I may eventually turn them off though.
I used
these which come in both the low and high beam size.
