Could be a few things, weak alternator, bad battery, bad wiring. If you have a subwoofer in your car with no battery cap that will certainly do it.
you might have a short in your alternator. In my car the headlights would dim when I put on the brakes or tried to use cigerette lighter to power up my phone.
You should dim your headlights within 500 feet of the car in front of you. The rule of thumb is, if you can see another car, dim your lights.
100 feet
When you get 300 feet from the car coming ahead.

i have two problems my dim headlights will not come on.and when go to put in gas it will flow back word make it seem like the car is full.
Check the grounds for the headlights.
Usually dim headlights are caused by a poor ground connection.
100 yards
At night a driver should dim his headlights when an oncoming motor vehicle comes within 1,000 feet. You should switch your headlights from full beam to dipped beam when a oncoming car passes. It is unsafe to leave your headlights on full beam as it blinds the driver of the oncoming car.
