Bluetooth Transmitter with a led that lights up when paired

Hi Due to responses to my other post about a bluetooth transmitter, I'm going to go as suggested, and look for a dedicated 3.5 mm audio bluetooth transmitter, but prefer one that has a LED that lights up once paired so I can use this signal as an input to the arduino. Most units seem to have the pairing light as part of the switch and changes color once paired, it would be easier to have one that has a seperate LED. If anyone know of such a unit it would be great if they could let me know or even a link would be ideal.

Thank you
