MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511122572 A) filed by Chandigarh University, Mohali, Punjab, on Dec. 5, 2025, for 'smart ambient-light-based vehicle headlight control mechanism.'
Inventor(s) include Dr. Priya Batta; Dr. Abhishek Kumar; and Dr. Prasenjit Das.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention provides an intelligent automatic headlight control system for vehicles designed to improve road safety and operational efficiency by eliminating manual headlight switching. The system employs an ambient light sensor integrated with a microcontroller unit to continuously monitor environmental light levels. Using calibrated lux-based thresholds, the microcontroller automatically activates or deactivates the headlights to ensure optimal visibility in semi-dark, foggy, or transitional conditions such as tunnels, dusk, or overcast weather. Sensor input is processed through an ADC or comparator, while an automotive-grade relay enables reliable headlight switching. Optional LED or buzzer feedback alerts the driver to status changes. This low-cost, energy-efficient, and easily retrofittable system operates without complex AI or GPS, reducing battery drain, driver distraction, and the risk of visibility-related accidents."
