OR IN ANOTHER WAY, IF A CAR IS MOVING WITH SPEED OF LIGHT & WE SWITH ON ITS LIGHTS, WHAT WILL HAPPEN?

When a car goes the speed of light it's mass is infinity so it's gravity is infinite and the entire universe gets sucked into it. That is why nothing with mass can go the speed of light.

Another way of saying it is that time would stop for the car and no light would come out of the headlights.

To a person in the car, the light from his headlights will appear to travel away from him at the speed of light, as he would expect. To a stationary observer, the light from the headlights will appear to move at the same speed as the car.

Time dilation causes this phenomenon; essentially, the person in the car is experiencing time in something like a super-condensed format... he literally experiences everything at once, and it seems to take almost no time to him.

You can look at it this way: If the car and the light are both moving at the speed of light (which they are, as a stationary observer can see), it will take infinitely long for the light to travel any distance from the car. However, the person in the car experiences time infinitely quickly, so the light seems to move away as it normally would.

First of all, you should specify the motion of the mirror with respect to something, or else the question may be unanswerable. Is the mirror moving at the speed of light with respect to the light source? Or with respect to the observer? Or with respect to the earth? Or to something else? Often these problems are posed without specifying reference points, and therefore typically generate lots of arguments among scientists and skeptics.
As to the car problem, if "we" are in the car and switch on the lights, the illumination will appear exactly as it always does when it is standing still with respect to the earth. Again, the question does not specify with what reference point the car is moving at the speed of light. Since it is at rest with respect to "us", it does not matter that is moving at the speed of light or any other speed with respect to something else.

the speed of the reflected rays move in the speed of light for the person sitting on the mirror.....for an outside observer who is at rest and watches the mirror move sees both the mirror and the reflection travel with the same sped)speed of light)

With the mirror,light couldn't catch up to it.
With the car,the light would accelerate for one thirty-billionths of a second to 1 cm then it would build up in intensity and burn out the emitters.

light will always travel at the speed of light, its a constant no mater what happens

depends what if any light hits the mirror, maybe you threw it into a black hole...now theres a head scratcher...
