My honest answer to this is (if you are not already doing so) to drive a car with the latest headlights- I used to really struggle to see where I was going in the Volvo with standard incandescent bulbs, whereas the LED projectors in the E63 are amazing and mean that even with my old man eyes I am confident that I can see where the road goes.
I found that replacing the inner reflective housing made more of a difference than dicking around with bulbs, but honestly lights on older cars are just crap.
