Turn off 12V cigarette lighter when engine is off?

[laramie4x4]

The cigar lighter on top of my dash has a battery symbol on it, and it is always on even when the engine is off. Is there a way to make it only on when the engine is running? Don't want to drain the battery if I forgot to unplug.

Here’s another thread of this where you’ll find the answer.
