Yes. Every single one. And the bathroom lights.
And if there is any Lite beer on board, it must be held to the window.
You caught me in a little hyperbole. Really though, prior to the low-down, dirty, rotten, *#!@% terrorist attacks, I barely paid attention to air traffic, unless I went to Gravelly Point (right at the end of DCA's main strip) to watch them take off and land. After the attacks, I noticed EVERYTHING in the sky.
Seriously though - these days they shine a lot more lights than before.
