I think one is lights. The other is placebo?. Supposed to be engine map switch but nobody I ride with can tell the difference. So it gets switched now and then just because it’s there. Kinda like the old Steve Wright joke, In my house there's this light switch that doesn't do anything. Every so often I would flick it on and off just to check. Yesterday, I got a call from a woman in Germany. She said, "cut it out!"
