Statistical evidence indicates that while traffic volume is essentially lower at night than it is during the day, accidents occur more frequently at night. The ADHL is theoretically said to prevent 91% of non-fatal accidents and 88% of fatal accidents that occur in the curves, resulting in minimal lighting at the site. Additional elements that contribute to accidents are mentioned in literature research. These include broken roads, people who disregard traffic laws, and the effects of bad weather like rain or clouds. To reduce the cause of the accident, the study developed a mechanism for adaptive static headlamp systems with dynamic capabilities. The mechanism consists of six light-emitting diode ADHL lights: two main lights on the right and the left, two right and left turning lights with small turning angles, and two left and right turning lamps with large angles while the setting is on or off. The selection of lighting is based on the minimum power requirements with the optimal light intensity, indicated by the size of the minimum light cover radius of the driver. The simulation of the mechanism at the 5°–40° turning position shows that the larger the radius of light coverage, the smaller the intensity of light that can still be seen well, so that the main light is adjusted to switch on the high beam at the big turning so the viewing distance can be reached further and when the small turning can be adjusted to the low beam condition.
