The lightbar on my truck is currently switched thru a relay, it's either on or off. I want to add a second switch that will turn the light bar on with the high beams AND I want to keep the existing switch to turn it on independently. Sort of a driving mode vs. plain lighting mode.
The diagram is what I came up with. My question is related to the area in the yellow circle. Do I need to worry about feeding power back into the relay? What if both switches were on? If either of these is a concern how to I isolate the two circuits? A beefy diode?
