Fug lites....
Boy am I glad I didn't get the fog lights and put them on. Those switches are poor. They aren't even moisture proof. Open toggles like that need to be encased in rubber boots. At least you can save your switches.....Good old Radio Shack has rubber boots for those. They screw over the threaded portion of the switch stem after the switches themselves are secured in the plastic handlebar mount, which, looks a little cheesey, but doable. The boots will render the switches splashproof and moisture proof but it looks as though the housing may leak (plastic housing that is). The switches will be immune to moisture. I'd also open the housing and apply soime di-electric grease to the switch terminals and the switches themselves in the plastic housing.
I always keep a tube of di-electric grease in the toolbox. It's good for bulb sockets or any electrical connection that has moisture present........No, it's not a substitute for KY Jelly.
