Abstract：The visual efficacy of high pressure sodium lamp and three widespread LED lights were tested under mesopic vision simultaneously and obtained the basic data of 30 samples.After screening and analysising the experimental raw data scientifically , 30 samples′universal parameter values of the reaction time are gained under the conditions of 4 lights in different road brightness levels .Universal parameter values were used to fit the mathematical process through spass software , and the visual efficacy function of the relationship between surface brightness and reaction time of high pressure sodium and three LED lights under mesopic vision was gained .After control analysis the characteristics and spectral of these universal parameter values and four kinds of lights , the main factors and wavelength spectrum which affect human reaction time under mesopic vision can be achieved .
