in WA we tend to get away with all kinds of lighting WHEN OUT OF TOWN. just don't get caught running bright spotties around town, or fail to dip quickly enough if a cop comes head-on.
Lots of people here run light bars on their roof rack. There are separate rules governing these, re off-road use only.
I run old style deep dish high polish 1 pencil + 1 spread IPF 900 with 55W HID conversion. The range on these suckers is incredible. Reflectors light up like car headlights at 2km!! but,,, I have to dip for large road signs as the reflection blinds me. Interestingly, my brother has the later series IPF 900XS (not as deep dished) which we put the same 55W HID in but they are notably not as good as mine.
I also have 1 pencil + 1 spread Narva with 130W halogen. The HIDs are near useless in fog & heavy rain, as they create a 'white wall' in front. This is where the more yellowish halogen are better & I have them mounted down low.
I also have a 12" LED bar between the HIDs that I use as a highbeam supplement/infill, but it too is an issue in fog & rain.
When way out in inland areas where there is very little to no traffic at night I turn everything on. DAYLIGHT ARRIVES!
NB. I still have a pair of 150W halogen light aircraft landing lights in my shed, but I don't use them anymore as the HID are as good for 1/3 the power. The aircraft lights are rated as 15V but run ok on 13.5V when driving (ya don't run them just on battery 12V with engine off), & you need really heavy cable to minimise any voltage drop. You could warm your hands at 6ft from those *******s!
