Brake light failure

Hello good I have a Hyundai Coupe 1.6 FX of 1998 and it turns out that I am fixed and the brake lights if I do not turn on those of position are perfect, when braking the light of the account is turned on and others (something that I do not know if it is normal), but when I turn on the normal lights to see at night the rear brake lights are lit with those of rear lighting, what failure can this be?
all the best

Hello, see if you have changed a bulb recently see that it is the bore, if it is correct then as sure you have a problem with some mass.

Friend is missing a ground cable .. Check if there is any cut cable .. I spend that once .. a bad earth can be .. disarms the rear focus and check if there are broken cables or lands that are not fulfilling their function .. oxides etc.

greetings

As they told you the most normal thing is that it is a lack of land but for this you do not look for a wire cable a cable to the earth plate of the rear focus one new and throw the other end to a mass bolt and already, it passes a lot is nothing of the other world, and answering your other question when one steps on the brake only this one should turn on any other light that turns on is no longer normal.
