PJR I don't want to get involved in you discussion with Hairy.
First of all the fog light rule is not new, like indication when exiting a roundabout it is being revisited to remind people of the rule now that the majority of vehicles have fog lights fitted.
Simplistically headlights are at specific heights to be seen over kerbs, roundabouts, centre reservations etc, they are also restricted in the height from the road, so truck lights must be below 1400mm from the ground.
All road vehicles must have 2 forward facing headlights with high and low beam, as
well as white side lights (parkers) and orange/amber direction indicators .
Fog lights are an accessory, that are low mounted for the reasons already indicated in other sections to light up the road surface under the fog.
Fog lights unlike spot or
driving lights can work with just parkers and are not connected to high or low main beam, spot or
driving lights must only come on with the main or high beam.
Using low fog lights in wet conditions cause the light to reflect back from the wet road surface which is why they should only be used in fog conditions.
Fog lights by nature of the design provide a spread beam (or should) that see's the kerb on both sides of the road. In real fog (as in Europe) you will understand that need. This design means that fog lights can and many cases will cause issue with approaching drivers.
I do not believe that the law is behind in the case of fog lights, there are valid reason for this law. The use of fog lights law is common to European law and miss use is not tolerated there.
If you want daytime running lights fit them, Volvo have had them for decades.
I personally have fog lights in my bull bar and would never use them knowing that they may/will blind on coming vehicles.
In my opinion, too many people use fog lights instead of low beam or dipped headlights, I am yet to understand why.
It would appear that those who use them do not believe that the manufactures headlights are good enough to light the road?
