At what speed do you outrun your headlights?
The math is surprisingly simple: At 55 miles per hour, you need about 500 feet to perceive an obstacle, react to it and bring your vehicle to a complete and safe stop. AAA’s research found that the most common halogen reflector lights illuminate only 300 feet on low beams.
Can a car headlights work at a normal speed?
Will the headlights work at that speed? Yes, they will. The light coming from the headlights will appear like moving away from you at a light speed—similar to what we experience when driving with the lights on in a normal condition. The speed of the light beam will be faster enough to race ahead of the vehicle.
Why do headlights not illuminate anything in front of the car?
Yes, they will under certain conditions. But the headlights won’t illuminate anything in front at that speed because the velocity of the vehicle, you (as the passenger), and the light is equal. If you are outside the car and facing the light while traveling at a light speed, you still won’t see the illumination because of the equal velocity.
Can a car appear to move at light speed?
Yes, they will. The light coming from the headlights will appear like moving away from you at a light speed—similar to what we experience when driving with the lights on in a normal condition. The speed of the light beam will be faster enough to race ahead of the vehicle. However, the distance will appear compressed in that high-speed condition.
What’s the best distance to adjust a car’s headlights?

How to avoid being blinded by another car’s lights?
Dim your lights when necessary. If another vehicle’s lights are bright: Do not look directly into the oncoming headlights. Look toward the right edge of your lane.
