1. A method for operating an electric tool system comprising an electric tool and a lighting device arranged separately from the electric tool, wherein depending on a value of an operating parameter of the electric tool, information relating to the value of the operating parameter is directly or indirectly transmitted to the lighting device by the electric tool; and wherein the lighting device provides, depending on the transmitted information,
i) a plurality of light pulses to be emitted, wherein a pulse parameter relating to a pulse duration of the plurality of light pulses and/or to a frequency of the plurality of light pulses and/or to a pulse amplitude of the plurality of light pulses and/or to a duty cycle of the plurality of light pulses depends on the value of the operating parameter; or
ii) a light pulse to be emitted, wherein a pulse parameter relating to a pulse duration and/or a pulse amplitude of the light pulse depends on the value of the operating parameter; or
iii) light to be emitted, wherein a light intensity of the emitted light depends on the value of the operating parameter,
wherein the value of the operating parameter is compared to at least one predetermined limit value and the pulse parameter and/or the light intensity are determined depending on a result of the comparison;
wherein the at least one predetermined limit value includes a first limit value, wherein the operating parameter is in a predetermined admissible operating range if the value of the operating parameter is less than or equal to the first limit value; and
for determining the pulse parameter depending on the result of the comparison, a value for the frequency of the plurality of light pulses is selected from two or more predetermined frequency values; and
the selected value for the frequency of the plurality of light pulses is greater the lower a difference between the value of the operating parameter and the first limit value is, if the operating parameter is in the admissible operating range.
