Abstract
In a vehicular lamp, a plurality of LED lines to which a plurality of LEDs are connected in series, are connected in parallel. The LEDs are arranged in a flat plane on a circuit board, the plurality of LEDs are arranged symmetrically with respect to a first centerline of the flat plane. Therefore, even when any one of the LEDs in the plurality of the LED lines becomes incapable of emitting light leading to all of the LEDs connected in series in the LED line to turn off, because the LEDs in the LED line are arranged symmetrically, the symmetrical balance of the LEDs shut down is maintained as an entire lamp, and the overall appearance of the lamp can be preserved.
