Light is a source of warmth, hope, and vision. In a time of darkness, it can be hard to see.

President Michael D. Higgins has led the Irish at home and abroad to take part in the #ShineYourLight initiative - bringing light into darkness in a gesture of global solidarity and hope.

Government buildings were lit up with a host of national and local public buildings across the island shining their beacon lights, along with Irish embassies and missions around the world.

#ShineYourLight/ #LonraighdoSholas called on people of all ages, to be as creative as they wish to either power their phone torches, flash house lights, leave a candle safely in the window or even put up Christmas lights, to participate in the initiative from wherever they are.
