Do some models have a white position light on the tail vs. a strobe?
If yes then does it have a power supply box?
If no, then the only way I have a position light is if someone had a bad power supply and did not want to spend the $6-700.00 to replace it and just ran straight voltage to a white position light. The box may be in the aircraft and the wires cut and bypassed or the box removed and wires spliced.
or, can a position light be inserted in the socket instead of a strobe bulb and the power supply just powers it as a steady voltage??
