No, all planes have those lights, and they all do the same thing... .
Welp........yes and no.......ie:
Tonight I saw a small jet leave the airport. Wing tip stobes flashing at the same time, 4 quick flashes than pause.
..........I can say without a doubt that this airplane was an early Citation.
Even Nav lights vary. In the US just remember "red-right-returning". This means that if you see a red nav light on the right and a green light to the left, the aircraft is approaching(returning).
In Europe, I think most aircraft have intermittent Nav lights now(they flash on and off)......any of you guys feel free to step in and chastise me on that info.....in addition to strobe lights. I know for a fact that Russian aircraft have this setup for the Nav lights.
On the some of the 30 series Lears a "recog" light is mounted in the nose of one or both of the tip tanks and on the 55 and 60 it's mounted in the upper tail facing forward. These lights are as bright or brighter than landing lights.
Although the helicopter you saw may have been a lifeflight helicopter, the only identification required by the FAA is a note on the flight plan, no special lights or markings.
The only real difference I've ever noticed is that choppers don't have the red and green wingtip lights.
.....look a little more closely

.....so I loaded up the plane and moved to Middle-EEEE..........OIL..that is......
