On my flight 2241 (Aeroflot/Rossiya Airlines) from St. Petersburg to Novosibirsk the cabin lights were blinking for the last 30 mins of the flight when the captain announced we stared descent, with some of the lamps being completely off. It looks that there may be some problem with either power supply of power distribution in the particular A319 plane, as all of these lights came on when we were on the ground in the parking position. Blinking lights are quite annoying, in any case.
