"Lighthouse" is a song by Irish boy band Westlife and it is the lead single from their second compilation album Greatest Hits (2011).

Band members Mark Feehily and Nicky Byrne discussed the song during a behind-the-scenes look at the music video shoot.

[2] The band's manager Louis Walsh revealed later: "Gary wrote that song for Elton John a few years ago.

[6] The full, high quality radio edit of the song was posted on their YouTube site on 10 October 2011.

[7] Robert Copsey of Digital Spy claimed: "It's probably the most grown-up sounding single Westlife have ever released.

It may not be the usual slow-tempo ballad but you will feel the touch of Westlife with the piano intro, uplifting choruses, soaring melodies, powerful post middle-8 key change and harmony-filled split vocals of Shane and Mark backed by Kian and Nicky."

[13] Filming for the music video of the first single began on 17 September 2011 and was shot in South Africa also like the album photoshoot.
