Abstract— Nighttime driving behavior differs from that during the day because of unique scenarios presented in a driver's field of vision. At night drivers have to rely on their vehicle headlamps to illuminate the road to be able to see the environment and road conditions in front of him. In recent decades car illumination systems have undergone considerable technological advances such as the use of a Light Emitting Diode (LED) in Adaptive Front- lighting Systems (AFS), a breakthrough in lighting  technology. This is rapidly becoming one of the most important innovative technologies around the world within the lighting community. This paper discusses driver’s (car and truck) needs given the environment and road conditions in the state of São Paulo (Brazil) using a survey applied to compare the needs of both truck and car drivers under different road conditions. The results show the potential and suitability of the methodology  proposed for controlling truck-related lighting in any emergent market.
