When it comes to props, generally if you paint something, throw in a few leds, and 'weather' it a bit no one will question it unless they're specifically looking to recreate it or otherwise learn more about it. Some very distinctive things like the Schick razor in Phantom Menace were borderline obvious as an item just about everyone has seen regularly, even daily for some, in their normal lives and yet 99% of the audience never would have noticed it unless someone pointed it out.
