Static bend lighting is an important feature of adaptive front lighting systems (AFS). With the improved side illumination it offers obvious advantages to various driving situations such as intersections, towns and curves. Experiments show that the detection distance at an intersection is nearly double for an HID system with static bend lighting (32m) compared to an HID system without static bend lighting (17m). These lamps can be integrated into the headlamp or realized as a separate lamp in the bumper. The changes of ECE regulations (R98, R112) and the introduction of a new 'ECE' cornering lamp regulation require the investigation of differences and accordances. The first part compares legal requirements and lighting needs for SAE and ECE cornering lamps. The second part presents the realization of cornering lamps/static bend lights positioned in headlamps including different light patterns and a discussion of various light sources. Comparison of legal requirements show that it is possible to have one adapted light distribution that fulfils all regulations for ECE/SAE cornering light and ECE bend lighting. Different reflector designs were presented for different mounting situations. It is obvious that the light performance of cornering lamps/bend lights essentially depend on where other headlamps elements are positioned. It was shown that bulb shields have a great influence on light performance that has to be taken into account for the reflector design.
