When coming from bright sun and also maybe wearing sunglasses the change going into the tunnel can be quite dramatic. My close calls have been with walkers exiting the tunnel in the same lane I am entering. That is coming at me. Very dangerous. I think brightening the tunnels is a good idea. I also think people walking in them is problematic. I know that there is a school of thought that you should walk looking into approaching traffic but that can be dangerous at the tunnel entrance when carts are approaching making a 90 degree turn into the tunnel which is much darker than the outside.
