PROBLEM TO BE SOLVED: To provide a vehicular signal lamp capable of enhancing visibility by changing irradiation width of light according to a surrounding environment.SOLUTION: In a vehicular signal lamp 1 configured by accommodating at least LEDs (light source) 5,6 in a lamp chamber 4 defined by a housing 2 and an outer lens 3 for covering its opening, a plurality of LEDs 5, 6 are arranged across front and rear two stages along an irradiation direction of light, and irradiation width of the light is changed by lighting on/off the LED 6 at the rear side while the LED 5 at the front side is being lighted. Also, another small housing 7 is arranged inside the housing 2, and the LED 5 at the front side is arranged in the housing 7. Furthermore, in front of each of the LEDs 5, 6 arranged front and rear, diffusion lenses 8, 9 are arranged respectively.

    【課題】周囲の環境に応じて光の照射幅を変更することによって視認性を高めることができる車両用信号灯を提供すること。【解決手段】ハウジング2とその開口部を覆うアウタレンズ3によって画成された灯室4内に、少なくともLED(光源)5,6を収容して構成される車両用信号灯1において、前記LED5,6を光の照射方向に沿って前後2段に亘って複数配置し、前方のLED5が点灯中に後方のLED6を点灯又は消灯することによって光の照射幅を変更するようにする。又、前記ハウジング2の内部に小さな別のハウジング7を配置し、該ハウジング7内に前方の前記LED5を配置する。更に、前後に配された前記各LED5,6の前方に拡散レンズ8,9をそれぞれ配置する。【選択図】図3
