My IPF 900's with HID conversion -one spot and 1 flood are more than adequate with excellent distance and good width.
Last long weekend over on Fraser, I was parked just above high tide mark and saw someone coming down the beach with just high beam and a light bar on the roof. Light bar was bright as hell but when he went past me, I looked around to see how far he could see, and it wasn't far at all. A lot of light just going no where and pretty useless in that situation. Obviously do not know what brand and whether it was aligned properly but distance is more important than width when looking for best way through the cut up loose sand south of Indian Head or where waves are washing up on the beach.
Also I am reluctant to alter the air flow any more into the intercooler scoop as the standard Nissan bulbar already creates turbulence and I'm certain reduces the efficiency of the intercooler. I have been tempted to buy a light bar and if I did, it would have to go on the roof.
