Hi Folks - thanks for this report. Please note the tag “feedback-logged” which indicates the Dev Team has taken in the report for triage. Next step is for them (or the manufacturer Carenado who was commissioned to create this product for MS-Asobo) to reproduce. If successful, status will switch to “bug-logged.”

same, hope they can reproduce.
The work around I found is that as soon as it starts flickering to switch off your landing lights and if you have the interior light on switch that off. The alternator seems to be fine keeping the battery charged with beacon, nav, and panel lights. I just did almost a 2-hour flight night flight and if I did the above it worked out. Just had landing lights on for take-off and landing.
It would be nice to keep landing lights on as most GA aircraft will under 10,000ft.
This happened to me also flying from HOPE to VANCOUVER but I think departing point and destination are probably not an issue. I noticed it because suddenly my 4 Logitech/Saitek instrument panels I had dialed into the 28L runway started to capture and drop the VOR and glideslope signals flashing on and off. I then noticed that the instruments in the cockpit were also flashing on and off.
I did have all the usual lights on. Havent tried it with lights off.
I’ve done multiple night flights now and it is an issue with having landing lights/too many on for an extend period of time and it slowly kills the battery. I have found that taking off with landing lights on and switching them off when no longer needed (though most GA leave them on under FL10) and then back on when landing is fine. I’ve done a 2hr flight with no issues this way.
even with landing lights off it doesnt last… is there anything that can be done in devmode to boost it back up?
What other lights do you have on? I have found that with landing lights off and dome light off it has been fine.
just the beacon and instrument lights.. unless the floating panel gtn750 also drains battery, because that flickers too
Possibly. I use it as is without the faux panel. But I will have panel, nav, panel, pitot, avionics, and only use landing lights for take-off/landings and it works. There is definitely a bug but if the aircraft uses the GTN750 as if it was actually in the plane with its old electronics/power I’m sure that would kill it. Try it without and see what happens.
I did some monitoring of the battery voltage. The pitot heat drains the battery most. But already second rank in draining are the NAV lights. Here is the ranking:
Pitot Heat
NAV lights
Fuel Pump
Landing Lights
Panel Lights
Beacon Lights
Engine Anti Ice
Also, if Avionics is not switched on, the battery will not get drained, regardless what else is switched on.
Avionics + Panel Lights switched on will still charge the battery.
I now totally agree having done several test flights that with lights off there is no power issue.
So it is a bug. If this was a real reality issue then I would expect warning signals. I think it only works over a sustained period with ALL lights off. Not good but a work around. No doubt this will be fixed.

With just panel and beacon lights I can fly for 3 hours and still use landing lights for take off and landing.
The NAV light is the bad one.

Try turning off as much of the electrical system as you can, this plane has a fairly weak 12v electrical system with a weak battery. Not every plane can have all the switches on at the same time 
I just another test flight. Everything on from startup, all lights, avionics, carb heat, flew around at night for ~45min. Flickering started. Tuner off landing lights and dome in the back. Flew around for another 40 minutes without issue. Turned landing lights on for landing and a long taxi. Probably were on for 7-10 minutes and did not get the flicker.
I don’t know if this is accurate of not as @jonasbeaver said this has a weak system. But I can do and have done long night flights now with turning off the landing lights/dome. The nav light stayed on the entire time as well as all other equipment. It would be nice to know if IRL owners upgraded the electrical system and if this is realistic for the model.
Maybe some documentation or POH to come with all aircraft… naaahhh that is crazy talk!
