Some lights on
 

I got a 1990 Camry, 4 cylinder and the Brake, Charge and Light lights stay on, the car runs fine.
Any clue what could be?

Thanks

What are "Light lights."

Do you mean the alternator charge light?

And the brake lights in the back of the car?

How long has this been happening? If the alternator charge light is one the battery is not being charged and would soon run out power (not be able to start then engine). Is this happening?

Some lights on
 

The Brake Light, the Charge Light and the "Light" light, (but all the lights in the back are working).
You're right, the alternator is not charging good, only around 11 v.
My girlfriend that use the car, and she said that this is happening for sometime, but now stays on.
The car still starts and runs.
I thought that in the case of alternator failure, only the charge light will be on.
Thanks

If all the lights come on at the same time and the alt is bad, suggest replacing it. A bad alt can cause the Brake light to come on, not sure about the other one but this is the place to start.

A working alt may fix all the other light problems.
