Strobes.
CASA, the FAA, Piper and Cessna all recomend that Strobes be turned ON just before entering the runway and turned OFF exiting the runway. The airlines do the same.
Anyone who has been taught otherwise received poor quality instruction from an instructor who also received poor quality instruction and has never considered his actions nor read up on the subject.
It is good airmenship to leave the beacon light switch on at all times. When the master switch goes on for the start the beacon is already operating, warning those looking that an engine start is about to happen.
At the end of the flight, if the master is accidently left on, the beacon light still operating will give a pilot the clue that he needs to go back to the aircraft and turn the master off, or be prepared for a flat battery the next day.
Do not forget to give a very loud pre-start call 'Stand Clear, Starting. That is a better call than 'Clear Plop'.
The Turkey of the year award :hittinghead: goes to those pilots who taxy out with their aircraft lit up like a Xmas tree with position lights, beacon, strobes and landing lights blazying - even in the middle of the day. At night - well who cares about any other pilots night vision!
For those who drive Piper retracts having the position lights on helps to dim right down those pesky gear down lights.
