ok.. so I was going to rewire the light overtop of the sink.... there is one black and one white wire.. no ground... I thought... no problem I can just run a ground wire down to the switch... no problem.... and then i made an assumption.. that since the lights breaker was off... so was the switch.... I was run... got a nice little shock.... the only thing that I could come up with is that one black wire goes to the breaker for the light and one doesnt... I dont know..... HELP!!! so here are some pictures of my light... (old light) will that work for me to run a ground down there?
