Bellbox stickers

Hi all, I have a replaced an old elmdene prima for a flashguard Xl on my property, it works perfect nice and loud and shiny, only issue is the cover has no logo, I would like to put a sticker on the box to make it look more professional. The most convincing stickers on ebay are ADT, the others stickers are obviously fooling no one.
All I want to know is if I can get into any trouble from ADT If i put one of their stickers on my sounder? sounds daft I know but just curious. The sticker of interest just says "ADT (R)" it doesn't have their number.
Is there any point, am I opening a can of worms? Is it best to just leave it blank?
At the end of the day the sounder works and will attract attention, I just think the sticker will make it look a bit better.
thanks

No ....where did you get the flash guard XL from ? Bet that’s a few years old ...

I bought it on ebay,its the xl plus version, Do you mean no as in its not worth it or no as in I won't get into trouble?
thanks/

You won't get into trouble, the sticker wont do anything, it won't improve your security but it will eventually look crappy.
Methinks its better to just leave it without one.

You could actually get into trouble if ADT could be bothered for unauthorised use of there logo.

It is unlikely, to be honest and secondly, unless its the ADT style and colours then it would look dubious at best.
