Is it because the two lights cancel out the interface? I have no idea.

I think it might be something to do with phase difference, it's been a while though.

I hope you don't find it too frustrating to get a hint rather than the answer - the key issue is that the light sources are 'incoherent' - if that doesn't ring a bell in itself, you should be able to look up the keyword in the context of interference in your textbooks or online.

So there's destructive interference.
