Swany,
We run both high and low... we run 4 HID long range lights up high and 2 HID wide areas on the bumper...
But we run the upper lights above the front window area and aim way out in front to keep the glare off the hood...
I agree though, lights and dust do not work... I hate night races for that very reason... you cannot run in someones dust like you can in a day race... unless you shut off your lights and just chase the other guys tail lights... but that is way illegal and sometimes even more dangerous.
