OEX Stop Light Switch (4-Pin) – Nissan 350Z HR / 370Z
OSL118
The stop light switch controls brake light activation and provides critical input to multiple vehicle systems. The OEX OSL118 is a 4-terminal switch designed for later model Nissan applications, delivering reliable brake signal operation and system communication.
When diagnosing brake lights staying on, not illuminating, or issues affecting cruise control and brake signal input, the stop light switch is a commonly inspected component within the system.
Multi-terminal stop light switches provide additional signal pathways for modern vehicle systems, including ECU monitoring and safety features linked to brake pedal input.
Common symptoms associated with stop light switch issues:
• Brake lights not working
• Brake lights staying on
• Cruise control malfunction
• Intermittent brake signal faults
• Brake-related warning lights
