What is this controller in my truck?

[Specop_007]

So pretty sure it has something to do with the lights, but not a clue how it works. I've pressed the Mode button, held it down, nothng seems to ever change.
No idea really what it is or what its for, maybe a controller for a light bar?




This is what it looks like when I turn on my lights, the 2 buttons light up.




And heres what it looks like when I press the power button.
