Parts & Vessels Illuminators (lights) do not function [Flicker/Blink for a second and turn off]

After launch of a craft, toggling the lights button for all lights or just the individual illuminator results in the illuminator blinking on briefly then off and and then ceasing to work.  This is the case for all lights in the Light group of Utility.

A simple craft to test was a MK1-3 capsule, Z-4K battery, and anything from the Light group from Utility.

Severity: medium.  Rovering in the dark is problematic
Frequency: high.  Always occurs.  Even after quick save and revert and game reload.

I have the same issue, it can be worked around by clicking "Revert to Launch", then they work. It's rather odd.

Same experience. Something odd with the illuminators

Confirmed.  placing craft on pad... no lights.  Select Revert to launch.... lights!!

All light sources such as landing wheels front lights to dome lights don't illuminate the environment or even the blinking light. It's just a gray color. It happens randomly, but when I reload the game it gets fixed, I can't find how to reproduce this.

I found that f5 f9 caused the lights to start working.

Yes, after launching directly from the VAB, lights do not work. Revert to launch will fix this.

@Jeq, merged your bug report.

[BlackholeKS]

Same issue. Quicksave and reload reliably fixes it for me, but results in the lights UI being in an incorrect state. I think this also might sometimes happen with landing gear.

Should be noted that the same issue doesn't happen with the interior lights of pods, which display correctly when turned on right away.

In this short clip, you can see me first load an earlier save in-flight, where the lights do work. I then load a new flight from the VAB and all of the non-landing-gear / non cockpit lights do not work.  They flash for a split second when "U" is first pressed, then nothing.  Do note that I removed the landing can's lights from the "U" functionality.

Also, theres no way to 'uncouple' symetry once they've been placed (ie, if you want one side to be red, and the other green), like in ksp 1. it was really useful.
