1. A vehicle lamp comprising:
a turn signal lamp light source including a plurality of light emitting elements independently controllable to be turned on and off;
a nonvolatile memory that stores a parameter for independent control of the plurality of light emitting elements;
a signal processing device configured to generate, based on the parameter, a plurality of turn-on commands independently indicating turn-on states of the plurality of light emitting elements at each time point by executing a software program; and
a drive circuit configured to drive each of the plurality of light emitting elements independently based on the plurality of turn-on commands,
wherein the plurality of light emitting elements of the turn signal lamp light source independently blink in response to a turn synchronization signal from a vehicle that alternately repeats at high and low in a predetermined cycle.
