That one pair of headlights are 2 low beam and 2 high beam so that make 4 lights

Low beam turn off when highs are on.. So that is not correct.

No they dont

No they dont

Incorrect, most do. Too much current draw with both lit on the common negative wire and also too much heat to dissipate in the lamp assembly. Look at car next time with blown high, it will only have the park lamp (if not blown too).
Big GU is correct in the technical respect.

Regardless off do or don't. .
In SA from the local plods mouth.
They class it as basically per globe / lense.
So a patrol has 2 factory driving lights.
An 80 has 4 factory lights..
A BA falcon has 4. Even though it's only 2 lights per say each housing has a hi/low beam and then a second hi beam globe and lense in the same housing.

Same here in QLD and was in VIC in my younger years. A light is the physical unit, not the filament count.

That was from the horses mouth Kallen. I can't argue with that. He did also say that this is something thats often overlooked if you are pulled up by the fuzz. They would usually just count one headlight as one.

Likely already said but I was talking with a trusted performance 4WD company (who do all form of mods including stretching) and the rule is for QLD, legally, nothing bigger than 33's. Apparently, a pat can't pass the swerve test.

Take the 35's with you on a trailer with trolley-jack, swap boots when off-road or run the 35's at risk of being dicked.

Yep. I have concluded that 35's are a definite no go. So this I will run the gaunlet with. Lol

I've been scouring the VSB14 guidelines and can't find this anywhere. I think I will send them an email and ask where I can find the ruling. I'm also thinking I can't find it because it may be a victorian rule, so it won't be in the VSB14, it should be via the vic government website or Vic Roads.

well bugger be sideways, you learn something new everyday....... although my park (side) lights are separate to the main lights.

So why is it that with HID headlights, when you first turn the lights on low beam, they take a while to get up to brightness, but when you switch to high beams, the brightness is instant?

The only thing I can find in all docs is driving light must be fitted in pairs of 2 or 4, or a single symmetrical centered bar.
