DDTV: There’s loads of brains in the McGeehin family – brothers Ronan (13) and his brother Eóin (14), are students at Coláiste Ailigh in Letterkenny.

And they wanted to develop an early warning system to tell motorists when the road surface becomes icy.

With in-car gauges not always accurate, the boys have come up with an incredible prototype which could save lives on our roads.

Watch this video to see their incredible idea on show at the BT Young Scientist of the Year exhibition in Dublin.
