When cleaning out the glovebox in my car I found a device that I do not recognize; neither does my wife so I have no idea where it came from or what it is used for.
It is a rectangular black plastic box measuring approx. 8cm. long, 3cm. across and 1cm. deep. at one end is a small torch bulb and beside it, projecting from the body of the device, a small hollow metal tube which appears to be designed to plug into something (like a tiny jack plug).
Inside are 3 AAA batteries. On one side is the word "reactivator" and a switch that when pressed turns on the light bulb.
Please can anybody tell me what this thing is and what it is used for?
Thanks; it looks similar to the de-icers pictured on the website but the rod is much shorter (1cm.) and it doesn't get hot. I've just noticed another tiny switch marked "on-off". Strangely enough the bulb lights up when you press the button even when this small switch is in the "off" position!
