ELECTRICA FAILURE LIGHT SYSTEM

Thank you so much for your valuable comments. It turns out the light switch lever was damaged; it seems to have burned out. So I'll have to find a used one, since new ones aren't available for that model. But as kikemec mentioned, once I figured it out, it wasn't that complicated. So thank you very much, problem solved! The solution is to replace the light switch lever, which is the same one that controls the high and low beams and the turn signals. It's a single piece along with the windshield wiper lever. Greetings and have a good day everyone...
