Look straight down at the back of the headlight assembly and you cant miss it. Clockwise is "up".
The allen key I have that fits is 6mm, unless my holder is marked wrong.
The Silverstars I just put in combined with adjusting the throw have helped a lot. Probably 40% better than stock and half as good as the HID kit. Until I adjusted them up they were much of an improvement over stock, just whiter and brighter. Adjusting them got a better throw and the SS's are bright enough to carry that far whereas the stock bulbs were not.
I agree, re-aiming helps tremendously!
Worth a try, but am surprised nobody has mentioned that will put your lights up into on coming traffic. It'll be a fine line of what is acceptable or not.
Actually, the headlights can be raised a fair amount before this becomes a concern. Fortunately, the beam cut-off point is pretty distinct on the S197's, which allows us to raise the aim, to a point, without bothering other drivers. I suggest re-aiming with a full(ish) tank of gas; and be aware that if there is more weight in the trunk, or rear seat, than typical, you may need to turn the aim down (counter-clockwise), a 1/4 to 1/2 turn. Obviously, at least for me, the "eye comfort" of other drivers is a primary consideration; it will be noticeable, to you, if the upper limit of the beam pattern is too high. Just be aware of where the light is reflected; can you clearly see the rear of the drivers head in front of you, or do you see any light on the drivers face, when on a two lane road? If yes, - then you've gone too high...
