The two transducer units are disposed on opposite sides of the short-circuit ring and electrically connected to it. The short-circuit ring has an opening, and the tag chip is electrically connected to both ends of the opening of the short-circuit ring. The indicator light unit is electrically connected to the output terminal of the tag chip. The indicator light unit includes an indicator light, electrode pads, and leads. The electrode pads are electrically connected to the output terminal of the tag chip via leads, and the indicator light is soldered onto the electrode pads. The indicator light uses LED beads.

Its shortcomings are: firstly, this type of electronic tag with illuminated positioning lacks protective upper and lower layers on its front and back, resulting in a relatively short lifespan; secondly, the layout of the tag antenna and conductive sheet in this type of electronic tag with illuminated positioning is relatively dispersed, meaning the compactness between the tag antenna and conductive sheet is relatively poor.
