Thanks for the post pswmom I know the kind of box you are referring to, but here what I was referring to.
I was putting the very obvious plate holders in question and I see something like Stealth Plate

I then figured the black box with the led and switch is the activation box as many of these plate cover systems have. I tow as well and have a brake controller but none of mine require a cigarette lighter or have an led and switch they are typically much more professional and hook directly into the brake control underneath the steering wheel just above the peddles.
The plates on that Yukon are not your standard plate mounts but clearly look like a sneaky plate hiding scheme. I am surprised he was not pulled over and ticketed for this if he drove for any length of time. JMO Is the black box in the photo I included the kind your husband was referring to? Just saying those plate mounts look awfully fishy to me.

It appears that DM installed the original version of the Ghostplate active plate obscuring system:

Ghostplate supplies this switch to control the obscuring; look familiar?

Anyone notice how dark the Yukon looks, even under lighting? Dark enough to be described as black like the truck witnessed in the Harley theft?
