Please help with lights in After Effects

It’s a… quite big. Hope you won’t have a problem to render it out.
Just to be clear, intensity of the second (closest to starting point) light must be negative so it kinda consumes energy of the first light.
Your video layers… I would make them 3D and pushed them back little bit on z-axis and give your camera little bit a wiggle on X and Y as it travels along the tunnel so 3D effect will be more noticeable. If the trick with lights will work out you may need to turn option “accept lights” to “no” for those 3D video layers because they gonna be to close to the light near the exit.
But it’s up to you. If you decide to leave them 2D make sure they are at the very bottom of the stack of your layers (no 2D layers in-between 3D layers when you’re using lights).
