I don't mean the LED doesn't light up I mean there is NO LED FITTED.
So in that sense ... the LED doesn't light up.. but only because it doesn't exist. I see the hole in the rubber mount... but there isn't an LED in the sensor itself. So there's no LED. And of course I cannot get the sensor to pair/sync/whatever.
This is the link to the sensor pack I bought

Am I mad? Is there something I'm missing? Or have I ordered some sort of dodgy knock-off product from Amazon.
Thanks.
