My SPF has the following problem, which started right after I drove through a thunderstorm that got the cockpit wet. The headlight toggle switch won't click down into the "headlights on" position. When I push it down, it springs right back up and the headlights won't come on. Parking lights click on as usual, and the headlights blink on/off when I click the dimmer switch (which I believe is normal). It's a Lucas 3 position switch. I'm thinking it's an internal mechanical switch failure rather than an electrical problem, and the timing relative to the rain is just a coincidence. Blind optimism? Could someone tell me how these switches fail? Thank you!
