Abstract	Ensuring safe driving in low-light conditions heavily depends on the effectiveness of vehicle headlights. Manually adjusting headlight intensity can be distracting and often suboptimal. To address this, the Automatic Light Intensity Controller (ALIC) system for vehicles is proposed. This system employs external light sensors to continuously monitor ambient light levels. Using the sensor data, a microcontroller unit (MCU) dynamically adjusts the headlight intensity through Pulse Width Modulation (PWM) techniques. This enables automatic adaptation to changing lighting conditions, thereby enhancing driver visibility and safety. The ALIC system also provides a smart lighting solution for indoor environments, aiming to optimize energy efficiency and ensure comfortable illumination. By utilizing a light sensor, microcontroller, and control mechanism, the ALIC system dynamically adjusts the intensity of electric lights based on the surrounding ambient light. This closed-loop feedback system ensures real time adaptation, reducing artificial light usage during periods of ample natural light and increasing it when necessary in low-light scenarios.
