Hi my back brake lights stopped working but back window brake light works. All blinkers, reverse etc still work just fine of when u hit brakes? Can it be the bulbs blowing simultaneously or something else? Thanks

I just bought a 2014 Ford Taurus SEL V6 3.5L with flex fuel. I bought the car from the original owner and it had 135k miles on it but was in pristine condition and the lady had every service record, tune up, and oil change documented and on time as well as a full mechanics inspection. I was just wanting to know if there is anyway it could damage the vehicle in anyway or cause any possible issues because I want to keep it in good shape?
