SAFETY AND DRIVING DYNAMICS WITH LEVEL SENSORS Microelectromechanical system (MEMS) accelerometers and gyroscopes are used for adaptive headlights and other automotive applications, such as tilt measurement and headlight leveling. It has been found that high-density discharge (HID) headlights improve the safety of night driving by projecting light further down the road and increasing the time available for reaction to problems. HID systems project up to 3,500 lumens, while older halogen systems | 0 | 182 | xinyinian1231 |
