Jn 1:8 ... Not was that-one the light, but that he-might-testify about the light.

Verse 8 has two phrases containing these 11 narrator words ... Ouk ēn ekeinos to fōs, all hina marturēsē peri tou fōtos (Not was that-one the light, but that he-might-testify about the light).

The 11 narrator words are bottom up tangent to the "the lights" under John and Jesus. The 5 words "Ouk ēn ekeinos to fōs" (not was that-one the light) are tangent to the "two lights" (the white equilateral triangles) under John. The last 2 words "tou fōtos" (the light) is tangent to the "one light" (the white equilateral triangle) under Jesus. The light under Jesus is the one the narrator wants John to testify about.
