There are two versions I know, a long version and a short version:

Long:

Chorus: This little light of mine, I'm gonna let it shine, This little light of mine, I'm gonna let it shine, This little light of mine, I'm gonna let it shine, Let it shine, let it shine, let it shine.

1. The light that shines is the light of love, Lights the darkness from above. It shines on me and it shines on you And shows what the power of love can do. I'm gonna shine my light both far and near, I'm gonna shine my light both bright and clear Where there's a dark corner in this land, I'm gonna let my little light shine.

2. On Monday he gave me the gift of love, Tuesday, peace came from above. On Wednesday He told me to have more faith, On Thursday He gave me a little more grace. Friday, He told me to watch and pray, Saturday, He told me just what to say. On Sunday He gave me the power divine To let my little light shine.

Short:

This little light of mine I'm going to let it shine Oh, this little light of mine I'm going to let it shine Hallelujah This little light of mine I'm going to let it shine Let it shine, let it shine, let it shine

Ev'ry where I go I'm going to let it shine Oh, ev'ry where I go I'm going to let it shine Hallelujah Ev'ry where I go I'm going to let it shine Let it shine, let it shine, let it shine

Hope it helps. God bless! Steve
