PO ran wires from headlights to install aftermarket fog lamps. Those are now removed and my headlights are dim even though I have the brightest bulbs. He also had the ring LEDs running in Audi style under headlights. Those I'm leaving since they look cool and too much trouble to remove. I am installing TWO new sets of fog lamps / driving lights. I had planned to just run all wires into the stock fog lamp wire that's dangling behind my cladding. Or do you think its better to follow the directions and install with switches and/or switches from another Isuzu? Typing from cell phone sorry for typos.
