Q: Broken taillights

The tail lights run on a couple of circuits so let's narrow this down first. There is a running light circuit where the lights come on at night and then the brake light circuit where a separate circuit illuminates with the activation of the brake pedal. If every light is out, the main fuse for the exterior tail lights may have blown. If the running lights do come on, but the brake lights do no illuminate, you may have an issues with the brake light switch located behind the brake pedal or its circuit. Have a technician trained in vehicle electrical systems inspect your tail lights to find the fault.
