A vessel cannot travel with the speed of light relative to another reference frame; however, it can travel at a very high speed that approaches the speed of light relative to your reference frame. Within the reference frame of the vessel the speed of light will still be c, so that the light from its headlights will still move away with light speed and will thus still be observed as usual for light within any reference frame. The speed of light does not depend on the speed of the light source; i.e. you cannot catch up with light ever. It does not matter how fast you move relative to another reference frame, the speed of light you observe will alwyas be c relative to the reference frame moving along with you.
