Abstract: Disclosed is to provide a design method and design system for a vehicular lamp, a program to execute designing of vehicular lamp and a record medium recording the program, which are capable of improving an efficiency of designing a lamp satisfying design conditions including performance conditions required as the vehicular lamp and restriction conditions given to each lamp. A vehicular lamp design system 1 includes: a database unit 2 having standard database 21 registering standard data of a lamp and technology database 22 registering technology data including shape templates utilizable as shape data; and a lamp preparation unit 3. The standard data selection part 31 of the lamp preparation unit 3 generates design data by selecting standard data from the standard database 21 based on given design conditions. The morphing control part 32 updates the design data by use of the parameterized shape templates of the technology database 22 and the like.
