Smart Vehicle Headlight Auto Switching and Intensity Control

Road safety is a crucial concern in modern transportation, with nighttime driving posing significant challenges due to improper headlight usage. Excessive high- beam usage can cause temporary blindness to oncoming drivers, increasing the risk of accidents. Manual headlight switching often leads to human errors, contributing to poor visibility conditions. This paper presents an intelligent vehicle headlight control system that automates headlight switching and intensity control using sensorbased technology. The proposed system incorporates Light Dependent Resistors (LDRs) to detect ambient light, Ultrasonic sensors to sense oncoming vehicles, and Micro-Electro-Mechanical Systems (MEMS) sensors to detect sudden vehicle tilts indicative of an accident. Additionally, a GPS and GSM module is integrated to provide real-time accident alerts, allowing for faster emergency response. By automating headlight control and accident detection, the proposed system enhances road safety and optimizes energy consumption. Experimental results demonstrate that the system operates efficiently under various conditions, ensuring real-time response and improved driving safety.
