Under normal weather conditions, be it in the day or at night, there is no need to switch on the fog lamps. This is because the light emitted from vehicle headlamps is sufficient to illuminate the road ahead. Switching on front fog lamps will not further improve forward vision under clear weather conditions. Some drivers have provided feedback that front fog lamps, when switched on indiscriminately, are intimidating and cause added stress to the driver in front. Switching on rear fog lamps unnecessarily may also cause confusion to motorists travelling behind you as the intense red light emitted could be mistaken as the brake light.
