you will be traveling at the same speed except you'll be able to see better

If you were in a vehicle going the speed of light and you turned on the headlights you would see the light from the headlights speed away from you at the speed of light.
Remember, when you ask these questions, you are in the world of relativity.
To you, sitting in your spaceship, your spaceship doesn't look like its moving at all. Instead, the universe looks like its speeding around you. So if you turned on the headlights, it would be the same as turning on your headlights when you were sitting still (actually its exactly the same)
To a viewer watching you speed by, they would see you turn the headlights on but it would never leave the socket of your headlights.
To you in the spaceship... it looks totally normal... you see the light shoot away into space.
What's to explain this lovely paradox? Einstein's theory of relativity... a bunch of strange things that happen because of this one little strange quirk in physics: the speed of light is constant for all observers. There is no relativity when it comes to the speed of light.
So the earlier poster is wrong... there is no 2x the speed of light. There is no light traveling half the speed of light...
How did we solve that paradox? Well there's a bunch of things involving slowing of time, space compression... go to wikipedia and read an article there... its too much for me to type it all out

You don't need headlights. At that speed, you ARE light! But even close to the speed of light, everything on your spaceship is relative to you. Everything would seem the same. Light would go just as fast, clocks run just the same. The only thing different to you would be the rest of the universe that you saw through the window. Light from suns in the front would be blue shifted. From the rear, red shifted. Their clocks would run slower, their universe compressed in the directon you are going through it (or it is passing by you) But the speed of light would always be the same. That's what Einstein's idea was all about.

It depends if the light from the headlights is traveling dependent on the car. If so, then the headlights are traveling at 2* the speed of light. If the light is independent, then the amount of light would build up on the spot where the headlights are until the car stopped (or slowed down) and would appear much brighter than it actually is.
Since I am not a physics major, I cannot tell you the exact answer, but those two should get you thinking.

According to Albert, the light from your headlights is speeding ahead of you at the speed of light!

Ugh. The universe ends. (my answer is not entirely joke. If you could observe the universe around you, time would appear to be progressing incredibly fast.)
The speed of light is a constant, so, even with your lights on no one would see you coming until you hit them...but that's beside the point, really.

Ok, firstly it is impossible 4 us 2 reach the speed of light which is 299792458 meter per second. If it's possible, please tell me. when u turn the headalights, only the light from the car will flash. You'll be travaelling at the same speed...

I will still be going as fast as light in my vehicle!
