I put Marchal driving lights on the car Greg did for me, and am driving in daylight with them on in addition to headlights for visibility/safety...I want to be seen. I just switched clear bulbs to amber. Found pair on e-bay. Never intend to drive in fog, and can switch bulbs out in minutes if in a situation I feel I need the extra illumination. The Marchals are a little larger and are the button/nipple glass kind, and I like the look.
