- Brake Lights Stay On: The switch can also fail in the 'on' position, causing the brake lights to remain lit even when your foot is off the pedal. This can drain your battery and confuse other drivers.
- Cruise Control Malfunctions: If your Tempest has cruise control, a faulty brake light switch can prevent it from engaging or cause it to disengage unexpectedly.
- Intermittent or Flickering Brake Lights: Worn internal contacts can cause the brake lights to flicker or work only some of the time, which can be just as dangerous as a complete failure.
