The national crisis has brought an increasing focus and appreciation of just how vital the role of lighthouses and essential maritime safety services is to maintain the security of supply chains and the commercial survival of our island, say the Commissioners of Irish Lights.

The organisation has made a video to pay tribute to health care colleagues as part of tonight's RTÉ's #ShineYourLight / #LonraighdoSholas campaign that asks that we come together as a country in this time of darkness to shine a light in our homes and show that light really can reach us all.

Everyone is encouraged to shine a light at 9 pm, 11 April to acknowledge their tremendous and heroic work.
