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.
No.
Full beam lights in foggy conditions will reflect the light directly back at the driver. Dipped headlights should be used instead.
The middle two lights should be on when you turn on the headlights.
ummm... your brake lights should ALWAYS work whether your headlights are on or not, that's how people behind you know you are stopping.
Low beam headlights and fog lights if the vehicle has fog lights.
Brake lights should NOT be effected by the headlights. Brake light function is completely independent of the headlights. Assuming you are not refering to the tail lights, or marker lights, which are supposed to come when the head lights are turned on. Not having brake lights when the head lights are on is a big safety problem and should be corrected.
Your low beam lights should be on when driving after sunset (twilight) and when it is raining. Some states require headlights or daytime running lights to be on in various conditions or at various times.You should not use your high-beam lights when you are closely behind another vehicle, or when approaching another vehicle head-on on a two-way road.
In fog you should use dipped headlights or front fog lights. Also you should use high intensity rear ( fog) lights.
When the headlights are on.
Usually no, Much of the high beam will be reflected back at you by the tiny droplets of fog possibly making it harder for you to see.
on the same switch that turns your head lights on...you should see a little pull switch at the tip, when you turn on the headlights pull it out...it will not work unless the headlights are on
i'm guessing the light switch is getting old and worn....good luck also everyone should have a manual for their vehicle, and the library should have a professional manual available...in the reference section, you'll have to make copies of the important sections...good luck :)
if you recenly replaced bulbs u may have installed them backwards they should be running lights and brake lights if this is the case they maybe installed incorrectly
