Ground vehicles AI lights. How to turn it on?

[YoYo]

Any idea how to turn on lights of truck (added by user, off road)? I have a night mission, 0 o'clock and the vehicles from the group added by user (jeeps, trucks) all have their lights off, meanwhile, traffic from the map has lights on. It looks a bit strange . Is it possible?

AFAIK, there are only a few ground vehicles in the game that have their lights modelled as light sources (not that traffic does not really have light sources, merely a light texture that is painted on the road in front of them, making it appears as light, but those "lights" aren't emissive, they don't illuminate, they do not cast shadows. 

So except for the vehicles that do have missive lights, you can't turn them on. 

Those that do, turn them on automatically when it gets dark. 

Since I've got a bird brain, I forgot which of the ground vehicles in DCS have illuminating lights; it's some kind of a truck, and the LUV Tigr.

Why so few illuminating light sources? Because they kill performance. Or used to. The new lighting that ED are working on (PG/SOH map) may make strides in lighting advancements, it's up to ED to tell us when this will trickle down to other maps. I'm still hoping for user-placable light sources. We'll see.

It's a pity, it would be useful to have an option to enable the external (road) lights to be turned on on all ground units in ME. In fact, Tigr came up as an example on the Forum in several threads when I was looking for something on the subject, but only Tigr was always mentioned.
