Yellow
If it's white, it shows that lane changes are legal, and that traffic in the adjacent lane travels in the same direction. If it's yellow, it indicates that passing is legal (when safe to do so) and that traffic in the adjacent lane travels in the opposite direction.
A galvanometer shows opposite deflection because the current flowing through it causes a magnetic field that interacts with the permanent magnet inside the galvanometer. The direction of the magnetic field determines the direction of deflection of the needle, resulting in opposite deflection depending on the direction of current flow.
If the green arrow shows for the direction you want to turn then you obey the green arrow, the red light is for all other traffic. The green arrow basically overrules the red light for the direction of the arrow.
You may turn in the direction the arrow is indicating. No other maeuvers are allowed.

The arrow on magnetic field lines shows the direction in which a north magnetic pole would be drawn if placed in the field at that point. This convention is used to represent the magnetic field direction moving from north to south.
You may turn in the direction the arrow is indicating. No other maeuvers are allowed.
It means that either turns can be made in the direction shown by the green light or that a stop must be made before turning in the direction shown. Either way, turns are permitted.
yes map projection shows true direction
