To operate a direction indicator lamp performing chained lighting control as an emergency brake lamp without requiring a special signal.SOLUTION: A lighting control device controls a first lamp unit and a second lamp unit each of which is constituted by including a plurality of light emitting elements 1 to 6. The lighting control device includes control sections 22 and 23 which control the plurality of light emitting elements 1 to 6 of the first lamp unit so as to be sequentially turned on with a time difference when a first signal 200R is given from a vehicle, control the plurality of light emitting elements 1 to 6 of the second lamp unit so as to be sequentially turned on with a time difference when a second signal 200L is given from the vehicle, and control the plurality of light emitting elements 1 to 6 of each of the first lamp unit and the second lamp unit so as to be substantially simultaneously turned on when the first signal 200R and the second signal 200L are substantially simultaneously given from the vehicle.SELECTED DRAWING: Figure 2

    【課題】特別な信号を必要とせずに連鎖式点灯制御を行う方向指示ランプを緊急制動ランプとしても動作させること。【解決手段】各々が複数の発光素子1〜6を含んで構成されている第1ランプユニット及び第2ランプユニットを制御する点灯制御装置であって、車両から第1信号200Rが与えられた場合は、第1ランプユニットの複数の発光素子1〜6を時間差で順次点灯させるように制御し、車両から第2信号200Lが与えられた場合は、第2ランプユニットの複数の発光素子1〜6を時間差で順次点灯させるように制御する。車両から第1信号200Rと第2信号200Lが実質的に同時に与えられた場合は、第1ランプユニットと第2ランプユニットの各々の複数の発光素子1〜6を実質的に同時に点灯させるように制御する制御部22、23を含む。【選択図】図2
