Hi. Just wiring up rear fog, have read the regulations, when activating my rear fog switch, it only comes on on dipped AND main beam (ie not by itself and not with sidelights)

whats the ‘controller’ i may need with reference to notes 3 and 4 in current IVA regs, ie when i turn my headlights all off, everything goes off right? When i switch headlights back on (forgetting that the fog light switch is presssed on still but actual fog is off) then the fog comes back on aswell. Though i do have a telltale warning light to warn me so, so do i need the ‘oops i forgot to turn of the fog switch’ controller as well?
