The vehicle light-emitting device comprises: a light-emitting element and a phosphor that emits light when excited by the light emitted by the light-emitting element.The vehicle light emission device emits light in an area within a chromaticity diagram of a CIE 1931 color system, wherein an area located in chromaticity coordinates below a confusion color line passing through a confusion color center and a first point representing a chromaticity point that meets a requirement for yellow-orange in an ECE standard, and an area R1 contained within an area R that meets a requirement for red in the ECE standard, overlap, wherein area R1 is defined by a first straight line up to a fourth straight line, which includes a first r-point (x = 0.6450, y = 0.3350), a second r-point (x = 0.6508, y = 0.3350), a third r-point (x = 0.7337, y = 0.2645), and a fourth r-point. (x= 0.7210, y= 0.2590) connects.
