No. As one approaches the speed of light, time begins to slow down. It is theorized that at the speed of light, in addition to other problems, time as we know it, is essentially stopped. Therefore, once you attain the speed of light, you may be able to, from your vantage point, turn on the headlights, but as far as the rest of the universe is concerned, for you, time has stopped so assuming we could see you, nothing would appear to happen. What would you see when you turned on your headlights? Nobody really knows, but it is believed that things may seem quite normal until you come to a stop and find that millions or billions of years had passed during your trip.
