PROBLEM TO BE SOLVED: To provide a light source lighting device, a direction indicator lamp, and a direction indicator lamp system, in which chained lighting can be achieved at lower power consumption by using a power supply of a simple structure.SOLUTION: A light source lighting device 100 is used in a vehicle lamp including light sources 5-5which are connected in series with each other to a constant current source 4 and which can be freely lit with power supply from the constant current source 4. The light source lighting device 100 includes: detection sections 6-6for detecting power supply to the light sources 5-5; and timer sections 7-7for sequentially lighting the light sources 5-5by lighting the light sources 5-5in response to power supply detected by the detection sections 6-6.SELECTED DRAWING: Figure 1

    【課題】簡単な構造の電源を用いて、低消費電力にて連鎖式点灯を実現することができる光源点灯装置、方向指示灯及び方向指示灯システムを提供する。【解決手段】光源点灯装置100は、定電流源4に対して互いに直列に接続されており、かつ、定電流源4からの電源供給により点灯自在な光源51〜54を有する車両用灯具に用いられる光源点灯装置100であって、光源51〜53に対する電源供給を検出する検出部61〜63と、検出部61〜63により検出された電源供給に応じて光源51〜54を点灯させることにより、光源51〜54を順次点灯させるタイマ部71〜73とを備える。【選択図】図1
