1. A method of controlling a brake lamp of a vehicle including an electric motor as a power source, comprising:
determining, by a controller, whether a deceleration of the vehicle based on regenerative braking through the electric motor is present during a hysteresis period between an off threshold as a reference for turning off a brake lamp and an on threshold as a reference for turning on the brake lamp;
in response to determining that the deceleration of the vehicle is present during the hysteresis period, determining, by the controller, a state of the brake lamp before the deceleration of the vehicle enters the hysteresis period; and
in response to determining that the brake lamp is turned on or off for a reason except for the regenerative braking before the deceleration of the vehicle enters the hysteresis period, setting or resetting, by the controller, a request for turning on the brake lamp based on the regenerative braking in response to the determined state of the brake lamp.
