Look on the back of the device for a label which might tell you the input voltage.
Does it come with an ac adaptor, these will normally have an output voltage label.
What's wrong with the fuse panel? Piece of cake to wire into, probably easier than making up a bridging piece to take power from the roof light.
It's a bit like not having a spare socket in your lounge so wiring your TV to the lighting circuit - it's just not the done thing.
