Doyal:
I completed my RV6 in June 03
I had the same question as you do now. From my prior night flight experience 
plus the advise of a close friend that has many ours as a pro in night flying 
this is what I did.
You need the lights to point down some what into the runway. Not far ahead, 
this is useless. In order to have a feeling for third dimensional depth 
perception you need to see the ground close by. If not take a look at how the landing

lights are aimed in a 737.
What I did is to aim the lights so they are almost parallel to the ground 
when the aircraft is in a 3 point position. I actually aimed the lights slightly

down in this position. If you can imagine (put a string) on the chord line of 
the wing tip, the light should have an angle of at least 15 deg down respect 
to the chord line of the wing.
I use two (one in each wing tip) GE 100Watt halogen sealed beams, p/n 
GE-Q4509.
I get them from Aircraft Spruce ($24.95 ea.)
Great candlepower and narrower beam. 
The first time I installed them they were too high. I had to re position 
them. I forget now what the exact angle is from 3 point position to flying 
position. I seem to remember it is close to 15 deg. But you can measure it in your

airplane.
