General Information:

Jesus continues his parable, in which he speaks of his teaching as light that he wants his disciples to obey and share with others. He speaks of people who do not know or accept his teaching as being in darkness. (See: rc://en/ta/man/jit/figs-metaphor)

be careful that the light in you is not darkness

"make sure that what you think is light is not actually darkness" or "make sure you know what is light and make sure you know what is darkness"
