The lamps are going out all over Europe, we shall not see them lit again in our lifetime.
Sir Edward Grey, Foreign Secretary, uttered these words on the eve of Britain officially entered the First World War. Exactly 100 years later we are inviting millions of individuals, households and companies to join together in a national moment of reflection.
We're encouraging everyone in the UK to turn off their lights between 10pm and 11pm on 4 August 2014 – leaving only a single light or candle for this symbolic act of reflection and hope.
A limited edition Centenary candle is available from M&S stores or online for £4, with all profit coming to The Royal British Legion.
We hope to light one million candles across the UK to remember each and every one of those Service men and women who gave their lives in the war to end all wars. Please join together with us to create a unique national moment for the United Kingdom and The Royal British Legion. Find out how you can get involved here.
Westminster Abbey will be leading the nation with a First World War vigil liturgy which will be broadcast live on the BBC.
We've put together some resources to help you organise a commemorative event in your local area. Find out more about how to organise a LIGHTS OUT event here.
LIGHTS OUT is a headline project of the cultural programme 14-18 NOW and was initiated by the Department for Culture, Media & Sport; 14-18 NOW is a curated programme of new art works across the UK that forms part of the official commemorations of the Centenary of the First World War.
