Abstract: To provide a vehicular lamp system capable of reducing a replacement frequency of a vehicular lamp. A vehicular lamp system includes a vehicular lamp having a plurality of elements capable of emitting light to a corresponding irradiation region and a detection unit that detects presence or absence of an abnormality in the plurality of elements, and a notification unit that notifies abnormality information concerning occurrence of the abnormality when the abnormality was detected in the element, in which the notification unit notifies the abnormality information with contents, which are different between a case where the abnormality is detected in the target element capable of emitting light to a predetermined region among the plurality of elements and a case where the abnormality is detected in the non-target element different from the target element among the plurality of elements.

Abstract: To provide a vehicular lamp system and a vehicular lamp which can reduce a replacement frequency of the vehicular lamp. The vehicular lamp system includes a vehicular lamp having a plurality of elements capable of irradiating a corresponding irradiation region with light and a detection unit that detects presence or absence of an abnormality in the plurality of elements, and a notification unit that notifies abnormality information concerning occurrence of an abnormality when the abnormality is detected in a target element capable of irradiating a predetermined irradiation region with light among the plurality of elements.

Abstract: To provide a vehicular lamp that can improve the degree of freedom in the arrangement position of a road surface irradiation unit. The vehicular lamp comprises a road surface irradiation unit for forming an irradiation pattern around the vehicle with light from a light emitting portion for a road surface; and a shielding part for covering the light emitting portion for the road surface when the road surface irradiation unit is viewed from the front. The vehicular lamp may further comprise a lamp unit housed in a lamp chamber together with the road surface irradiation unit, and the road surface irradiation unit may be turned on and off interlocked with the lamp unit.
