To provide a vehicular lighting fixture which can suppress distant visibility in front (front direction) of an own vehicle deteriorating as, in the process of returning to linear travelling from curve travelling, when a driver turns the line of sight frontward of the own vehicle, the front of the own vehicle stays relatively dark.SOLUTION: A vehicular lighting fixture 10 includes: travelling state determination means 31 for determining whether or not the road where an own vehicle VO is travelling is a curve; lighting fixture units 40R, 40L capable of forming a light distribution pattern which can change luminosity in each angle direction in a predetermined region; and a lighting fixture unit control unit 34 for controlling the lighting fixture units 40R, 40L. The lighting fixture unit control unit 34 controls the lighting fixture units 40R, 40L so that, in the case where the road where the own vehicle VO is travelling is not determined as a curve by the travelling state determination means 31, a first light distribution pattern is formed having luminosity distribution in which the luminosity on the vertical line is the highest and the luminosity lowers toward left and right both sides from the vertical line in the predetermined region.SELECTED DRAWING: Figure 5 【課題】カーブ走行から直線走行に復帰する過程で、運転者が視線を自車の前方に向けた場合、自車の前方が相対的に暗いままとなり、自車の前方（正面方向）の遠方視認性が低下するのを抑制することができる車両用灯具を提供する。【解決手段】車両用灯具１０は、自車ＶＯが走行中の道路がカーブか否かを判定する走行状態判定手段３１と、所定領域に各角度方向の光度を可変可能な配光パターンを形成可能な灯具ユニット４０Ｒ、４０Ｌと、灯具ユニット４０Ｒ、４０Ｌを制御する灯具ユニット制御部３４と、を備える。灯具ユニット制御部３４は、走行状態判定手段３１によって自車ＶＯが走行中の道路がカーブと判定されない場合、所定領域に鉛直線上の光度が最も高く、鉛直線から左右両側に向かうに従って光度が低下する光度分布を有する第１配光パターンが形成されるように、灯具ユニット４０Ｒ、４０Ｌを制御する。【選択図】図５
