Lighthouse (G.R.L. song)

"Lighthouse" is the third single by American-British-Canadian girl group G.R.L., and the first single following the death of group member Simone Battle, who died in 2014. The song features songwriting credits from Lukasz Gottwald, and Henry Walter, with production credits from Gottwald and Walter under their production monikers, Dr. Luke and Cirkut. The track was released on January 15, 2015. "Lighthouse" was recorded in the memory of Battle.

The song's accompanying music video was directed by Daniel Carberry. It features footage and photos of Battle during her time with G.R.L., while the group sing in a room filled with hanging light bulbs. "Lighthouse" was supposed to be the final single released by G.R.L., as the group disbanded in June 2015. However, the group reunited the following year with the intention of releasing new music.
