A vehicular LED lamp monitoring/controlling system includes a vehicular LED lamp having first and second LEDs. A selection/control unit is connected to and controls separate activation of the first and second LEDs and is connected to a malfunction detecting unit that detects operation of the first and second LEDs. The second LED is activated when the first LED operates abnormally. A power control unit can send a control signal to the selection/control unit to control luminance of each of the first and second LEDs. A vehicle speed monitoring unit connected to the power control unit reads a speed of a vehicle on which the vehicular LED lamp is mounted. When the vehicle is still, the first or second LED provides normal luminance. When the vehicle is moving, the first or second LED provides reduced luminance.
