You need to make sure you understand what your what your trying to achieve with your lights first...

My understanding as to why rally lights are on general in front or on the hood is you want them low for high speed driving and visibility... we have 6 of which the 4 bigs ones will be used to fill the space down the road and be aimed subtly in different area (off set for crest or dip or long corners) and the two lower ones will be closer cornering lights... also being at the front of the car we will not need to worry about the light splashing off the hood or windshield and causing glare....

I think high lights are for off road slower speed longer throughs... pre runners, baja, etc...
