Abstract

To achieve visibility improvement and reduction of sense of incongruity in a vehicular lamp using LEDs. A lighting control device for controlling the on/off of a light source having a first and a second lamp unit each with LEDs including: a control part that generates a control signal for controlling the emitted lights of the lamp units; and a light source drive part for driving the lamp units based on the control signal; where the light emitted from the two lamp units driven by the light source driving part is such that each luminous intensity decreases from a first value to a second value which is smaller than the first value within a common period, and each luminous intensity decreases to the second value during the common period maintaining the relationship that the luminous intensity of the first lamp unit is lower than that of the second lamp unit.
