6.6 Dim Lights

Headlights that are dim or gradually getting dimmer generally indicate a problem with the battery or charging system. The red alternator warning light may come on as the lights are dimming. In either case, the engine and accessories are running off of the battery alone, and will soon discharge it altogether.

If possible, do not turn the engine off, unless you have the capability to jump start it. There may not be enough power in the starting system to restart the engine. Instead, turn off as many electrical consumers as possible. This will reduce the current drain and will allow the car to be driven further before you lose all battery power.
