You’re right, I got the words mixed up but the principles are the same.
Ok, my headlights are incandescent but my indicator for the high beam is LED. I have a 3-way switc, Off Lo and Hi positions. Main Beam IN, Hi and Lo OUT. Indicator has a positive and negative wire. Does anyone want to sketch a diagram for me? I have some extra diodes I can use if they are needed. I’m easily able to adapt wiring diagrams I see but LEDs are throwing me off. These circuits have diodes going into LEDs sometimes but not always. Not sure what the rule is.
