Tail lights stay on when ignition is off...

Tail lights stay on when ignition is off...
...and it's draining my battery.
Tail lights always stay on. One of the two filaments of each bulb always stays illuminated even if car is completely turned off. Everything else works fine.
Any idea?
Thanks.

I had a car do that several years back. It was the little switch the brake pedal engages/disengages. It was broke and the car thought the brakes were on all the time. Inexpensive and easy to check, I would start there if you have not already.

Thanks for your input though.

Easy way to check is to step on the brake pedal.
If the light gets brighter, then it isn't your brake switch.

Yeah, I stepped on the brake pedal and the light does get brighter: the heavier filament lights up which is not the one that I have a problem with. So you're right, it can't be the brake switch.

OKCMustangGT, you were right!
I thought it was the running light too, but decided to unplug the brake switch for trouble shooting purposes. And lo and behold, the light went out. So it was a bad break switch. (even if the lights were dim).
Thank you all,

What Year Mustang?
Part Number of Switch Installed?
Either Wrong Switch or Installed Switch Incorrectly.
The Early Switches are a Bit OF Weird.
But Some Further Details Would BE Helpful
Pic of Switch as Installed Would Be Great as Well!
