There are probably - depending on precisely what car / platform - probably NOT fuses associated with individual lights, no fuses to check.

Late model BMW have an external light monitoring function that sends frequent milliamp pulses through all external light circuits to notify of a failed bulb - a continuity check.

A fuse protects against over current - short circuits - and that is accomplished in late model BMW by electronic circuit-breakers that reset automatically a few times. Then you must replace the module serving the function.
Scepticism and Animal Faith (1923)
Scepticism is the chastity of the intellect, and it is shameful to surrender it too soon or to the first comer: there is nobility in preserving it coolly and proudly through long youth, until at last, in the ripeness of instinct and discretion, it can be safely exchanged for fidelity and happiness.
