In town, using dipped beams, the load is more like 150W,

How can foggy conditions result in so much more load? A pair of front
foglamps will be the same power as a pair of dipped headlamps and the
rear foglamps will only add 21w each which will only push it up to
about 200w total

'cos most cars, idiotically, only allow you to use the fog lights when the
headlamps are switched on.
