Embarassed
Lets say that you are able to reach the speed of light. When you turn on your headlights, nothing out of the ordinary will happen. You will merely see the light speed away from you at the speed of light. It would be the same as if you were standing still in your car and turned on the headlights.

This is one of the must incredible things about the speed of light (c) - it is constant for everybody. Even if you were an onlooker and you somehow saw the car go by, it wouldn't happen at twice the speed of light, it would still happen at regular (c). Going further, since the speed of the light viewed doesn't change, then what does? The time. If you are able to go near the speed of light (like .9999 times), time would go more slowly for you (compared to normal, but you wouldn't notice anything. If you look at the outside world, time would appear to be traveling faster. For example, going .9999 times the speed of light, traveling for one year would actually be 70 years for anyone else. If you were able to reach the speed of light, you will have esentially stopped time, and if you were able to go faster than the speed of light, there would be an inertial frame of reference in which you would be travelling back in time. This is actually a very touchy subject, i highly recommend reading more about it. There are some very interesting videos and books by Stephen Hawking on youtube that you can watch, both about light, relativity, time travel, all of that.

Amazing cheers
