Usually the Nav lights are on at the gate. These are the red and green lights to show port and starboard.
Before the aircraft moves or starts an engine, the beacons are turned on. These are the upper and lower red lights that flash.
Once ready to taxi, the taxi lights are turned on. These are usually located on the nose gear leg.
Upon entering the runway the wing strobe lights are turned on and are kept on untill the aircraft exits the arrival runway.
The landing lights are also turned on before entering the runway and are turned off above FL100.
I think thats the general order anyhow.
