The brightness of a headlamp depends on three factors: bulb, reflector and lens. In the development of the prism headlamp presented here, the improvement of the reflector was attempted because it has a relatively higher degree of freedom in design than the other factors. The reflector was shaped so as to collect as much light as possible from the bulb and was combined with a round shaped prism lens to control the light. As a result, a compact bright and unique-looking upper-beam headlamp, which greatly reflects light forward was developed.
