Check the power at the fuse box with a test light.check if the is power at other components.check fuse able link under hood near battery arn,t blown,check switch at brake pedal has power.

take out the dome light and see if that stops the short> if it does replace the dome light.

Check all tail light and brake light bulbs, look for any that may still work but look darker than the others, make sure to check the center brake light bulb on the rear shelf.

its a bad connection

Make sure you are using the correct bulb numbers per manufactures recommendation. Diff types of bulbs even though they fit and light up will give light monitor false readings. You may have a malfunctioning light monitor which I have seen on a few of these models.

The types of bulbs used in tail light have two coils, one for brakes and one for running lights, so there should just be the one brake light bulb to replace in the brake light assembly

The tail lights or the brakes light are out.

Means you have a taillight, brake light, reverse light, license plate light, or 3rd brake light out.

If you are talking about a picture of a car, with lines at the rear of the car, that is your 'tail lamp failure' indictor.

This tells you that one of your brake lamps, or a parking lamp in burned out, or otherwise inoperative.

it means you have a rear tail or brake light out.
