I did not go all scientific and measure 25 feet back etc. Pretty sure my driveway is not level... I just faced the garage door, maybe 3-4 feet back, lowered the headlights about a half turn of the screwdriver. If I still got many people flashing me (and not just one every 8 vehicles because he thinks my LEDS are bright) I repeat.

I faced the garage door because I do not know which way to turn to raise or lower, so I needed to see it on the garage door moving up or down
