Can Anyone Identify These Parts?

[Dansch06limited]

I bought a set of gauges for my hayabusa build & after they arrived i seen these 2 boxes mounted on the back. They are actually mounted to the gauge stay/ bracket. I've had a few types of illumiglo type gauges & these have them as well but I know these boxes are not for them. Does anyone know what these are and their purpose?
Thanks

Do you have special lighting on the gauges?

What are the wires coming out of the gauge unit for? Those are not stock.

Not stock. All I got unfortunately.
