Blinking Fog Lights On The Move

Hello to everyone. There is no problem with the headlights when I do not emit gas while the vehicle is idling or moving. But when I press the gas, the brightness of the left fog light increases and decreases like a wink. What could be the problem?

There may be an electrical problem, first disconnect the fog lamp bulb and check the sockets. may have oxidized or loosened and cause such troubles. Have the vehicle checked for battery and charger voltage values.
