I'm not sure what you searched for...there are articles and vendors for lights all over the web. For example, just quick search on Amazon for motorcycle fog lights produced pages of hits.
If the lights you buy don't have a switch, you can find one of those easily in the same place.
If you need brackets to hold the lights onto your forks, ditto. Or, pattytrue mounted a set to the radiator, which you can find in the thread here: https://www.hondarebel3forum.com/for...t-awesome.html
And, of course, any of the resellers like Revzilla, etc. would have lights and switches. Also light bars, if that's the way you want to go.
As for power, I believe--based upon the fuse diagram below--that the auxiliary circuit can handle 7.5 amps, which might be enough, depending on what lights you choose. If not, you could run a wire back under the tank to underneath the seat and tap into one of the circuits there.
There are quite a few YouTube videos on installing auxiliary lights on motorcycles; there's no real difference in the process between auxiliary and fog.
You should be able to find everything you need to get started with a little poking around and then have specific questions about problems you encounter.
