When using the turn signal to indicate turning direction at night, all lights shut off randomly, leaving you with no way to see where you're going. This includes all cabin lights so you can't find the switch to turn the lights back on. This happen regularly. This has been detailed here: https://www.tundras.com/threads/auto-headlights-shut-off-with-turn-signal.22968 It seems Toyota knows about this problem already, as well as the fix for it, but won't voluntarily recall the vehicles to address it.
