<How do the 86 and up turbo headlights work? I thought the inboard light <was a fog light. My Haynes manual says it is a driving light (Euro). What <is it on the American market? Fog, driving, or high beam? None of the above. It's just another marker light and comes on with the 'parking' lights. I run a slightly higher wattage bulb in em and use em as 'city' lights. -glen
