Question

In figure , one car is at rest and velocity of light from head light is C, then velocity of light from head light for the moving car at velocity v,would be

Answer 1

If observer sitting in car speed of light will remain equal to $C$ because that is the relative velocity.

But if a stationary observer stand outside the car the speed of light will increase as $C+v$

Where, $v$ is the speed of car.
