Check the third break light?
If the light comes on only when you press the brake, it means one of your lights doesn't get brighter with all the rest of the taillights. I've seen cars with their brake lights illuminate normally at night (when the taillights are dim), and then the person presses their brakes and one or two don't get brighter. They just stay at their normal illumination as if the person didn't press the brakes in the first place.burchard said:Did you figure you light problem out ?. I have the same problem. The blown light comes on and all the lights in the car seem to be OK.
