Default Re: Technology related anachronisms on TV and in films etc.

A recent episode of Foyles War featured a large country house being used for the training of spies etc.
Several modern looking self contained emergency lights may be seen over internal doorways. They have been covered up or painted to match the light green walls, but still look out of place.
One can also see the dust marks on the wall above the lights, caused by the modest but continual heat output.

Some premises did have emergency lighting then, but this consisted of standard "mains type" incandescent fittings supplied from a central battery.
And not fittings containing a battery and a miniature fluorescent tube.
