There are nav lights out there sufficiently simple and non-critical
in design such that someone can make an LED retrofit for the bulb that
gets the light to meet the spec - despite the difference in emitting
surface geometry and directional characteristics.
Motor vehicle lights are not as easy to make LED incandescent-retrofit
bulbs for with achievment of legal requirements being maintained.
