The rules, concerning the use of lights, in the country you are operating, control... However, also common sense also prevails.
If you are flying for an airline then their FCOM will provide guidance concerning this matter.
If you are still in flight training, your school's flight training manual will provide guidance too.
However, generally, any time the airplane is taxiing... taxi light on. Aircraft stopped... taxi light off.
Cleared to enter an active runway to line up and wait... landing and strobe lights on when taking the active. Take note... if the runway is entered from opposite sides, delay turning on your lights until the line of illumination will not blind the crew of the aircraft on the opposite side.
Strobes lights? If LVPs are in effect... leave them off as they create a nuisance to your fellow crewmembers as well as crewmembers in other aircraft.
Runway vacated... turn off landing lights, and strobes as soon as possible as to prevent visual distractions to other aircraft operators.
