Australian Design Rule 50 (ADR50) covers the fitment of fog lamps to vehicles. From the DOTARS website:
"The intention of this Australian Design Rule is to specify the photometric requirements for front fog lamps which will provide adequate illumination for the driver of the vehicle without producing undue glare for other road users."
Now I have long been in absolute awe at the number of VX and VY Commy drivers who don't understand what headlights are for versus the foglights (call them driving lights if you must except all that means is you address the same statement except it's ADR 45 or 46). Many have personally met Aussie Pete who slows down and gives them the high beam from behind for extended periods or gets the 500+ watt reply in oncoming traffic as I pass
So, it's time to attack the issue at the proper forum. Do what I did - send a complaint to the department of Transport and Regional Services (see www.dotars.gov.au
website) about the VX/VY Commodore fog lights which I believe are by far the most glare producing lights of their type.
As a matter of interest, get a VX/VY driver to operate their high beams and then their fog lights while you stand at a distance of 100-200 metres. I was astounded to find little difference in the glare I experienced.
