Two sets of power coming into bathroom lights.

Ok, I ordered a new bathroom vent with a fan and I was digging around for a way to route power to it. My one bathroom light has two white and two black power lines coming into the light, but nothing going out from it, very strange... The other light has only one set of wires, but it's next to impossible to tie into it.

Could it possibly wired for a fan and they just tied off into the light?
That would be sweet, I can find no other logical reason for the double wires.

Here's a pic... The 2 wires that are coming into the bathroom light are coming from the direction of the speaker, which right below that is the breaker box. The kitchen light has 2 wires, but it appears that one wire jumps to the light over the sink, and the sink light heads towards the stove exhaust fan. I'm so confused.

I guess the main question is, is it ok to tie the fan into the double wires on the bathroom light? I hope so, I have a $270 fan headed my way.

It doesn't make sense that it's part of a "string" because it's the farthest light away from all other lights. The wires definitely come from the direction of the fuse box, but continue no further than the light. The other bathroom light has a single wire that come in from another direction.

Are you sure that it is not one white in and one white out plus one black in and one black out. One light in a string of lights? (String = 2 or more.)

The wires probably go to the switch/light and out to another switch/light.

No wall switches in my camper, the switch is on the fixture.
