SkyYacht;
Yes and No.
Yes your headlamps would be on and anyone stood infront of your car would see the light from the headlamp (slightly before being splattered into a million pieces!)and no you would not see the effect of your headlamps being on (assuming you were the driver) as the speed of your car will not add to the speed of the light being emitted; which means if it was dark you would not be able to see where you were going and would mostlikely end up killing yourself fairly quickly (at the speed of light perhaps!)
