PROBLEM TO BE SOLVED: To provide a headlight tester having high precision by interposing a color correction optical filter for absorbing a measurement error factor by various optical components, in the headlight tester. SOLUTION: Concerning a headlight tester for measuring light distribution of a headlight, when combining a plurality of color optical filter characteristics and measuring distributed light intensity by the combined optical filter, in order to reduce an error generated by various optical components, each color correction filter having a reverse characteristic is interposed, to thereby constitute a headlight tester having high precision.
