Aging of general population structure has become one of the major issues in various social change these days in Korea. So, many researches have been performed to develop elder friendly devices and vehicle for older drivers. In this study, one of headlamp system for elder friendly vehicle, adaptive headlamp under rainy weather is being developed. Prototype adaptive headlamp were manufactured using D2S(High intensity discharge bulb) light source. Illuminance and luminance distribution of adaptive headlamp are investigated to evaluate its performance. Forty six subjects of two groups (drivers under and over age 65) participated in experiment. The questionnaires were performed about various driving habits and conditions with all of subjects. Glare index and forward visibility were evaluated by observing in driver's seat against oncoming test vehicle with three kinds of headlamps such as halogen, HID and adaptive headlamp. From the results, Illuminance and luminance distribution of adaptive headlamp were much lower than others in the near field. Glare of adaptive headlamp for adverse weather was superior to those of HID headlamp at 10~20m ahead. Forward visibility performances of adaptive headlamp was comparable to those of HID headlamp.
