it from Mazda car.
i think also that it is a lamp ballast, because it had picture of a hand with red line over it, like you are not sopose to touch it.
It could be as simple as being a power resistor. There are only two wires, and it doesn't look like it has an earth connection to the mounting lugs. Also the braided wire insulation and what looks like a ceramic spacer where the wires go in imply it runs hot. It could be for running light or dim -dip headlights (https://en.wikipedia.org/wiki/Automotive_lighting#Dim-dip_lamps)
