YZF 600 Side Light problem

I have just spend 6 hours trying to solve a problem with my side lights and was hoping someone could help me with my next step.

I had no side lights rear or front but headlight was fine.

I figured out that I only have 0.5v going to them, I joined a new wire directly from the battery live to the rear side light wire under the seat and both came on.

I am wondering if the switch is likely to be at fault or shall i run the new wire ive put in to the side light wire just as it comes out the switch instead of the battery?

Thanks
