I see no problem in having 6 lights.
I've had that many before...I love the light.
In NJ now, we are only allowed two sets of lights, say, a fog light set, and a driving light set, etc....even if they are covered, etc.
When I had many lights, I used to aim them at different points, close/fog/flood, mid, and long range points, so I'd have side lighting for suicidal venison warning, fogs to undercut glare, and longer range points to evenly light up the rest of my path, etc...
Currently...I have no extra lights...just about 5 sets in the garage, and I'm feeling my way through the dark with the crappy 9004's that the Owner's Manual says are 9007's.
