[Closed] A call to Exposure USE Joystick/Cannondale HeadSIght users

I've acquired a Cannondale HeadSIght light (the one that integrates into stems on their Bad Boy bikes) which I believe is simply a reworked Exposure Joystick MaXx light in a different housing. The unit was defective but I've resurrected it to working but I'd like to charge it up fully ready for use.

What I need is a kind owner of one of these lights to tell me what voltage the charger outputs and if the socket on the light is centre-positive or -negative. A quick peek at the charger will reveal all.

Thanks for your time 🙂
