Question about aircraft lights in DCS......

Is there any impact to gameplay (specifically enemy fire) based on whether you have external aircraft lights on or not? I see a number of DCS streams on Twitch or YT videos where people go lights out before heading into a target area and I wasn’t sure if that was just an ode to what would happen in real life or if there were actual implications for not doing so.

AFAIK the AI can identify/see your aircraft better or quicker than without external lights turned on.
