Yes, when driving in foggy conditions you should use your headlights which allows oncoming drivers to see you at the earliest possible moment. However, for safety, you should not use your highbeams [bright] as the fog will reflect back much of the light, reducing your ability to see into [through] the fog.

low beam
Not use their high beams and drive dramatically lower speeds.
False. You may confuse the opposite way driver of your real location.
Increased
Use low-beam headlights. When visibility is restricted, a driver's natural tendency is to activate the high-beam headlights. When driving in fog, this further impairs visibility because the high-beam illumination reflects off of the fog and back at your vehicle.
No, you should not use high-beam headlights at all in heavy fog.
Slowly with low beams.
You don't want to use high beams in foggy weather or snow. It actually makes it more difficult for you to see as the light reflects off the snow or fog.

Fix My Headlights is a great place to go to correct foggy headlights. They are very trusted and can do a very good job. I do not know anyone who has used it but it seems good.
No. Either use your regular headlights since they help other drivers see you. Also, slow down.
