Does anyone know what these are?

Does anyone know what these are?  When we took the rear license plate holder off it was wired in with a black and white wire.  The holder was blocking the button to open the rear hatch and also blocking the lights that are supposed to light up the tag.  We then noticed there is another one like in on the front also.  Don’t know if they were added on or if it came with them.  Any help would be appreciated as we aren’t sure if we can just take them off.  Especially the rear one.  They both look the same.  Rectangular with a small box and a long box.  The one is the photo is the one on the rear license plate holder.

Here is the front one and where it’s located.

The look like concealed signal pickups for a radar detector.

JFP in PA, 

Do they work with a radar detector?  Would it be ok then to take them off?  My husband wondered if they might be a jammer to block radar or laser...

Could be, but if the radar detector/jammer is no longer in the vehicle, removing them should not be an issue.

 

But a question occurs:  Does the vehicle have a cruise control systems that sense how far away the next vehicle is so it can slow automatically?  If it does, they could be the sensors for that......

Looks like a K40 Laser jammer. Not the best one out there.
