Mounting traffic advisor LED bar

[jj46]

I have a traffic advisor LED bar that is typically installed with suction cup mounts on the inside of the back window.  The issue is the defroster causes the suction cups to not stay for more than a couple days.  I've searched the inter webs a bunch and haven't found any kind of production mount available.  Unfortunately I haven't apparently been creative enough yet to come up with my own solution.

 

Any ideas/photos/products to mount these light bars in the cab?  Really hate to cut the headliner, and even then not sure what I would anchor to.

Aggressive double sided tape?

Yep, If I have to, that's an option.  Just wondered if anyone knew of any bracket system or anything else.
