The gas cooking appliance includes a burner, a flame detector for detecting a flame of the burner, a gas valve that controls gas flow to the burner, a control knob coupled to the gas valve and rotatable to control the gas flow to the burner and a lighting system for emitting different light signals depending on the position of the control knob. The control knob is movable between a closed position where no gas is allowed to pass to the burner and an open position where gas is allowed to pass to the burner, the open position comprising a plurality of operable positions, wherein each operable position is related to a quantity of gas passing to the burner. The lighting system includes a power control assembly cooperating with the control knob and electrically coupled to a lighting device. The power control assembly is also connected to the flame detector so that the lighting device only switches on, according to the gas quantity passing to the burner, only if the flame detector detects a flame.
