[Ford] Full Beams
A blue semi-circle with straight lines coming out of the side indicates that the vehicle’s full-beam lights are switched on.
When you activate the main lights the full-beam will also activate and produce a much stronger beam of light pointing forward.
It is common (and law in some places) not to drive with these on when facing another road user.
To turn these on and off it’s usually the backward and forwards motion of the stalk that the lights are on behind the steering wheel.
