there is a real strong possibility that both bulbs are burnt out. The bulbs are dual filament; one for the tail lights and one for the brake lights. On a ten year old car its probable that one bulb burnt out some time ago and you didn't know it then when the other one burnt out suddenly you have no tail lights.start by replacing both bulbs. I think that will fix your problem. If not, take it to a technician as there may be a problem with a ground wire or corrosion in the circuit.
