Lights go off at distance < 0.3 nm, they change on ships from directional to dot lights

[Jagohu]

"Generic" lights, where the ground object is only indicated by a single light dot (many vehicles, some ships like Ivanov, Yakushev) go "off" when the object is closer than 0.3 nm. Way to test: put in one or more vehicles at night and look at it, while zooming out. Close up you will see the dark shape only to get the light when the camera is 0.3+ nm out.

Also these "dot" lights are not ideal for ships as they display red-green and top lights when moving. A ship with modelled directional lights (ie. Elnya) and viewed from close-up (within 0.3 nm) will display the red-green lights, for ~0.3-0.4 nm both are visible, but beyond that only the "dot" at the middle of the object.

At least for civilian vehicles there should be a headlight/tail light.
