at what velocity is moving the light of the headlight?

According to Einstein's Theory of Relativity, time slows as speed increases. Light travels at the speed of light. As your car reaches 90% of the speed of light, time on board will slow down to 10% of the speed of time. When you turn the headlights on, the light will stream away from your speeding car at 10% of the speed of light, which will be 100% of the speed of light to an outside observer. Because of the slower time, the light will appear to be travelling away from you at 100% of the speed of light.
The same thing would happen at 99% of the speed of light: The light streaming from your headlights would be 1% faster but still be travelling at light speed, and look like light speed to you as well.
Travel at the speed of light is impossible for anything but zero-mass particles like electrons and photons. Your car would need all the energy in the universe. But if it could make light speed, the light would obviously be travelling at light speed. And it would look like light speed to you because your mad, road-burning, fuel-consuming mind would at last be stopped. (Yes, if light was conscious, it would not be aware that it was moving at all.)

this question has been asked so many times...(per theory) if you are driving your car in
space or on the earth and turn your headlights on...well since theory is that if you reach
the speed of light you become light therefore your car and you are no longer a solid
visible item. So therefore there will not be any headlights to turn on, you wont be there
to turn them on so therefore the answer is NO.
In the matter to time stretching...this is so the human mind can comprehend the speed.
At 186,282 mps you would be moving so fast so you could cover that distance in 1 second.
So in essence time does not change you are just fast enough to get more done in a second
so a second seems longer.

Relative to the car, it's stationary. Relative to an observer outside the car, it and the car are both moving at the speed of light.
You might be inclined to think that it's moving twice the speed of light, but that's not correct. Light is a wave, and a wave generally moves at a fixed speed through it's medium. Think of the waves coming off of a boat. While the boat is moving slower than water waves, the waves radiate from the boat in all directions. As soon as the boat exceeds the speed of water waves, there are no waves ahead of the boat, and there is a wake angling from behind the boat. Sound, and light waves behave in a similar way.

It is obvious that the light from the headlights is moving faster than the speed of light. This is because the gravitational pull of the sun effectively "pulls" the light from the sockets, and makes it go at the (speed of light) * (2). This is the fastest form of traveling currently known to man.

OK, I'm tired of showing people, both mathematically and logicly that you can not travel at the speed of light. so guess what, I am going to say OK, you have a souped up V8 will all the extras and break the speed laws of man and nature at get to light-speed.
Now, there you are, a point (lenght=0) with undefinable mass (you have to divide by zero), but we will call it infinite to make things a bit easier to understand.
Well, guess what, you are now a black hole! Light can not escape the warping of space-time around a black hole, so the light from your headlights are traped there.
Not to mention what the gravitational forces do to you and your car.

The speed of light.
You must understand that space and time change but the speed of light never does. In everyday life at slow speeds a meter or kilometer is always the same length and a second is always the same amount of time, but speeds change. A rock thrown at 10 m/s by a person running at 10 m/s is going 20 m/s where the meter and the second that measure it are unchanged. But at really high speeds things get strange. The rock thrown at 270,000 km/s by a person running at 270,000 km/s does not go 540,000 km/s, it only goes 298,343 km/s, while the length of a kilometer and duration of a second change. It flies in the face of reason, it must be wrong, but experiments have proven that it is not wrong and really does happen. There is no magic speed where things change from normal to relativistic. These strange things happen at slow speeds too, but the effect is microscopically small so we don't notice it. But the amount that length and time change by gets gradually more and more as the speed gets higher and higher. And the closer to the speed of light you get the larger these strange effects get, until AT the speed of light these effects get infinitely large, so that times stops and length shrinks to zero!

The light from your headlights would be traveling at the same speed as your car. The light would be staying in your headlights so no one could tell that they were on.

The light of the headlight is also moving at the speed of light. This is what proves that space & time must be curved.

Easy; your turbo car is not traveling at the speed of light. Your car has mass and therefore it would take an infinite amount of energy to reach c.

I think that, if your car was moving at the speed of light, it would be light itself.
