Check the fuses and relay to make sure nothing blown off while charging the car lamp or something. These electrical issues arent very easy to troubleshoot, but when you get there you feel OMG how can i miss that.

If still light remain on, get the computer check done to find the real problem. As it might possible that this light is coincidental appear when you charge lamp but its pointing to something serious/major.
