This is the most logical explanation to me (at least I would like to believe it more than the alternative). The mirror heater mats are very common, and some have LED lights. There are all kinds of them, 6x6, 12x12, built-in, glue-on, etc.
And if there were indeed a 2-way mirror/surveillance device there, wouldn't it be more logical to install it in a more clandestine way and without LED lights?
