Jn 1:9-12, 8:12, Rev 21:23
In the Old Testament, God had the priests build a lighthouse in the tabernacle. (Ex 25:31)
Ex 25:31 And thou shalt make a candlestick of pure gold: of beaten work shall the candlestick be made: his shaft, and his branches, his bowls, his knops, and his flowers, shall be of the same.
Jesus is the true light, the Christ, who gives us life. (John 1:9-12, John 8:12, Revelation 21:23)
John 1:9 That was the true Light, which lighteth every man that cometh into the world. 10 He was in the world, and the world was made by him, and the world knew him not. 11 He came unto his own, and his own received him not. 12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
John 8:12 Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
Revelation 21:23 And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof.
