If you're in a vehicle going the speed of light, what happens when you turn on the headlights?

I don't like to go fast,prefer to do things slowly ...but I always have the lights on (unlike Georgie who likes them off-for obvious reasons) ....extra special squeezy hugs x

Because of the prevailing winds at that particular latitude. As for why they move faster it's basic physics. If you shine a flashlight, it is traveling the speed of light. If you use the headlights on your car, the light is traveling at the speed of light PLUS the speed of the car.

In this imaginary situation, you will still see your headlights working the same way as they normally do. Without going into tricky mathematics, just recall the fundamental postulate of special relativity: \nThe speed of light is CONSTANT in all inertial frames of references (considering the same medium). \nSo, the speed of light will still be the same in the frame of reference attached to your vehical, which is an inertial frame, because it is moving with the (uniform) speed of light!

As you travel faster and faster, time for you slows down, and length contracts. From your point of view, when you measure the speed of light, it will always be the same. An observer standing still with respect to you and the beam of light could measure your speed at 185000 mps and the speed of light as 186000 mps, and say the difference in speed is 1000 mps. But that is relative to them. The speed of light will always be the same for whoever measures it, no matter how fast they are moving.\n\nSee the website below for more about relativity.

All these answers are wrong. Light moves from each source at a speed we'll call one. If you are traveling at the speed of light, then anything that leaves you at the speed og light will be traveling the same. Now while you will not see far with your headlights, they may well provide sufficeient view, as they are ahead, to give you sight enough to drive. But you shouldn't think about changing direction. Those sorts of speed are highly unstable and could rip your car apart

the speed of light travelling into a medium with a higher refractive index will slow down. if it is travelling into a medium with a lower refractive index, the speed will increase.

The speed of light is invariant---no matter how fast or slow its source is moving, the speed of light remains unchanged (...please don't ask 'why?' because nobody has the vaguest idea) If you're in spaceship going at 99% the speed of light and shine a light outward in any direction, that light will move away from you at the speed of light, no faster, no slower.\n\nWith regards to the answer given that mentions the Doppler effect. The FREQUENCY (wavelength) of light is affected by the speed of the light source (Doppler effect), but frequency has nothing to do with the actual velocity of the light itself.

I would not recommend driving at the speed of light.  There is a very good chance that you will get pulled over by the cops, and unless you have a very good excuse, the will most definitely give you a speeding ticket.  Since, in most states, the amount of the fine is directly related to the speed you are traveling, most of the money you earn for the rest of your life will be going to paying off the fine.

Of course they'll work. The question is if you will see them. You can't travel at the speed of light, anyway, or physics is wrong, so nobody would be able to give you an answer. \n\nAssuming you were just really close to the speed of light, you would still see them. Einstein discovered that the speed of light in a vacuum is constant to ALL observers, no matter how fast the source of light is going relative to the observer. So at any speed, you can see your headlights just fine.

No there is no 'summation' of speeds involved with light.  Light is Electro-Magnetic Energy, although light travels as particles as well as waves.  In this Universe the speed of light is a constant, roughly 186,000 miles-per-second, or 300,000 km/sec or 300 Mega-Metres / sec.  Unless some POWERFUL external force acts upon light, it cannot change speed.  This entails the gravity of black-holes and such. (Not even light can escape from them.)\n\nA vehicle might weigh somewhere in the neighbor-hood of 3,300 lbs. (Approximately 1,500 Kg, for those of you who have not learned to count properly, just yet ...)\nCheck out da' math ...\n\n60mph = 100 kmph = 27.77r mps. \n(1,500 Kg x 27.77r mps) / 9.81 mps = ~ 4,246 N\n\nI doubt, very seriously, that a little over 4,000 Newtons is enough force to even put a dent in the factor of light-speed.  For more info, look-up Einstein's Theory of Realtivity' (Although I believe 90% of it to be short-sighted ancient crap ...)  This subject is covered in it ...\n(umm covered in Einstein's Theory, not copvered in crap .. which err .. is the same thing at times ...

The speed of light is indeed a constant.  What's important is that it is a constant to every observer.  If you are traveling toward a light source at 1000 m/s, you will measure the light's velocity at 300,000 m/s.  If you are traveling AWAY from the light source, it will still measure 300,000 m/s.\n\nLight IS the absolute speed limit. (Of this universe anyway)

Interesting quatum phenomenon question.  The lights would come on, but they might appear strange to an observer due to the Doppler effect.  You, inside the car, would continue to see a headlight 'beam' because light's speed is a universal constant and not dependent on the speed of the source.  However, traveling beyond the speed of light in conventional space is not possible, to our knowledge.  For one, it would require infinate energy.  It would also cause macro-scale collapses in casaulity (effects happening before the cause).  To date, these bizzare effects have only been seen on quantum scales.

Well theoretically you wouldnt be able to travel at the speed of light. At the speed of light yoru mass would become infinite and time would virtually stop for you. But at the speed of light the light would still be infront of you. Think of it this way if you are in a race and the runner directly infront of you is traveling at the same velocity as you you would neither fall behind nor would you catch up. So the light would be in front of you.

Neglecting the lengthy derivation of why light speed travel is impossible, the first postulate of relativity is that light has the same velocity regardless of how fast you're moving.  So, at ANY speed you can achieve in your car, when you turn the lights on you'll see the waves moving away from you very very quickly.

Think of Einstiens theory of relitivity E=((MC)squared) Where C = the speed of light and M = th electrons flowing from the electric source to the bulb = E (the ability to do work) wich results in theroy the light bending around the vehicle eirgo the light bends becaus both the light and the vechile are travling at the same speed.

Its very sensitive question.., And i ll explain u very easy way...hmm...for light time of travellin is in fractions. though we assume the rocket is travellin in velocity of light, for that particular time light takes rocket is in static(0 speed) and travels to is own speed..and travels faster than de rocket. Assume this way.., u have already switched on de light before the rocket starts...and slowly tends to reach the velocity of it own head light, will u think the velocity of head light will go down....?? no , absolutely not...it travels as always with respect to treating rocket is in static(0 velocity)..

Friendly reminder also that your bright lights are blinding me.  Hasn't it become a traffic law in some states that if you aren't traveling at the speed limit you should move over allowing others doing the speed limit to pass?
