This paper presents the development of CAD system for the design of lens of the Turn Signal Lamp that can model and simulate its optical performance. The system consists of three main modules: skin surface modeling module. inner lens modeling module and optical performance simulation module.<br/> Skin surface geometry can be modeled by the input of data file and inner lens can be modeled by the input of only four parameter using its geometric characteristics. Also light distribution pattern, the barometer of optical performance, is generated by means of finite ray tracing method.<br/> The system display modeled geometry, ray tracing and generated light distribution pattern.
