I prefer using the fogs to illuminate the side of the road. I do quite a bit of rural driving and find them to greatly improve nearby road lighting. Frequently have folks flash their lights at me thinking I have high beams illuminated. My bulbs are legal wattage and properly aimed so I know that is not the case. I added the Bosch Euro headlamps a few years ago along with SilverStar bulbs and find that change to be dramatic. May not be the best headlamps I have ever had for reach and pattern but they are much more than satisfactory.
