Fog and high beams on together?

Fogs ON indication in Combo Meter still function...
Option to have IGN source power the relay coil side tap from the Towing Battery Charger Relay tap.

 

Yes, easily doable with the methods covered. Also really dumb. What are you hoping to accomplish? Fogs are a short range wide pattern light, they blow out your distance vision with foreground light, which doesn't matter for their slow speed poor weather designation. High beams are a distance light designed for long range high speed, that is only effective with good long range night vision, which is defeated by high intensity foreground light like that of running your fogs when unnecessary.

Understanding your lights and when to run which lamp at which time is going to perform far better than running everything at once because you have no idea what you are doing and handicapping all your lighting abilities due to a complete lack of automotive lighting understanding. So yes, you can do those mods. I admittedly did, then realized how counterproductive they were and never used them. It's a complete waste of time.
