the visibility
In California, the appropriate distance to stop behind another vehicle at a red traffic light is typically about one vehicle length or at least 3 to 5 feet behind the vehicle in front of you. This distance allows for safe maneuvering and visibility, particularly in case of emergencies. Additionally, drivers should ensure they can see the rear wheels of the vehicle ahead touching the pavement.
Time required to do what? To move from one place to another, divide the distance by the speed of light.
The image seen in a plane mirror appears to be the same distance behind the mirror as the object is in front of it. This is because light rays reflect off the mirror and create a virtual image that appears behind the mirror at the same distance.
inside the bonnet behind where the bulbs are there will be a big plastic cap and if you twist it you will have access to the cluster of bulbs.
The green light on a traffic light means to go ahead. If you "get the green light," you have permission to move ahead on whatever project you are dealing with.
it depends on if you were paying attention or not
In the United States, I am unaware of any minimum distance required from a window. There may be a local code where you live or work that establishes a requirement.
The distance from Deneb to the earth is still somewhat uncertain. One 2008 study puts the most likely distance at 1,550 light-years, but there is still a considerable uncertainty of more than 10%. The reduced parallax uncertainties do not rule out a distance as close as 1,340 light-years or as far as 1,840 light-years. Deneb is the farthest first-magnitude star from Earth. (The number of years required for its light to reach earth is the same as its distance in light years.)

Light energy IS required for Photosynthesis
For headlights that need to illuminate a long distance, the bulb should be placed deeper within the headlight housing to allow the beam of light to project further out ahead of the vehicle. This positioning helps to focus the light and extend its range, improving visibility for the driver on the road.
