I obviously means that there is something wrong with the alternator or battery. When both lights are on 80 percent of the time its the alternator. Either your belt fell off or your alternator went bad.
Alternater may not be charging would be my first thought.
broken belt
Probably the alternator. Have it checked if it is charging.
There are several warning lights on a 2008 Honda Civic. The main lights are for the brake system, air bag system, check engine, tire pressure, oil pressure, and battery power.
Most of the light on the dashboard are Warning Lights; different warning lights that might flash up on the dashboard. Some of the more common warning lights are shown below. 1 = Oil pressure warning light 2 = Battery charge warning light 3 = Brake system warning light 4 = Engine warning light
Alternator has/is going bad.
Possibly a bad alternator (the system is not charging the battery).
Brake lights draw their energy from the vehicle's battery.
you don't really know unless you get the vehicle tested...most likely it would be your battery or your brakes
I had this same problem with my !995 Galant. It turned out to be the alternator.
That warning light means a light bulb is out. Check all of your brake lights (including the brake light on the rear dash!)
The fuse box cover labels them
