U-HAD could save lives

U-HAD could save lives


A U-HAD (universal headlight auto dipper) is devised in such a way that the high beam of the headlights automatically switch to dipper mode when the oncoming vehicles are at a distance of 50 metres from each other and the modes are reversed within five seconds of the vehicle’s crossing thus accomplishing the purpose of preventing accidents at night. The project is part of NITI AAYOG and AIM (Atal Innovation Mission).

Student of Class 9, Sanad Baligeri was struck with the idea of this device when he was returning home late one night in 2016, when the high beam of the on-coming traffic was very bright and his mother found it difficult to drive. “The very next day I read in the newspaper about a fatal accident that took place at night due to the glaring bright headlights of the on-coming vehicles and so I decided to work on this project,” shares

Sanad. He adds that the aim was to make a device with the capability to automatically handle the switching of high and low beam modes of a vehicular headlight, without the manual intervention of the driver. He says: “The device’s precisely programmed sturdy circuit senses the light intensity of a vehicular headlight; it is not affected by the ambient light, further strengthening the efficacy of the device.”

His other teammates Sumedh Prabhudesai and Lekhraj Surlakar assisted him in assembling of hardware and designing. And they also helped in talking about the idea during their interaction with Prime Minister Narendra Modi via video conference on June 6 this year.

The basic project was ready in 2016, and in 2018 it is upgraded with latest technology and already installed in a vehicle in June. ATL in charge, Chintamani Shirodkar of Dr K B Hedgewar School, Cujira informs that the device has been fitted on trial basis in Sanad’s mother’s two wheeler and had been functioning perfectly since.

“We now have plans of producing ten more units and fix them in different types of vehicles amongst our acquaintances for a thorough trial of the product,” concludes Shirodkar.


The prototype is just installed below the battery and from there the relay wires are connected to the headlight above; just below the prototype is the sensor which is exposed out so that it senses the oncoming vehicles bright headlights.
