What's the exact problem? No light turns on or they simply don't turn on in the wanted way?

In the first case I'd consider pin assignment.

In the second one it's the logic. In particular I think the sec_1 definition is not correct.

This one would lead to more common traffic light behavior:

sec_1: STD_LOGIC_VECTOR (3 downto 0) := "0000";
