A method for operating a lighting apparatus of a vehicle. A temperature of the light source is recorded while the first light distribution is generated, a temperature change of the light source which is expected to emerge during the transition from the first to the second light distribution is calculated. Should the calculation predict that the transition from the first to the second light distribution would rise to an excessive temperature leading to a temperature above a threshold value in at least one critical region, then the power of at least one of the semiconductor elements is reduced during the control of the semiconductor elements implemented for generating the second light distribution, such that the temperature in the at least one critical region of the light source is not expected to exceed the specified threshold value as a result of the transition from the first to the second light distribution.
