Alright...so I as you know just swapped to the front end of a 2001 RS and put in the Hella 500s with the Kartboy brackets. And it just occurred to me that I have no idea how to aim these things. All I know is that I should be 25 feet away from a wall on a flat, level surface. But then what? What am I looking for in relation to the headlights? Should they be higher, lower, etc?
