Reverse light switch

Reverse light switch

The reverse light switch activates the rear reversing lights when the transmission is shifted into reverse gear, alerting other road users and pedestrians of the vehicle’s backward movement. It also provides input to additional systems such as parking sensors, rear cameras, and automatic transmission control logic. Reliable reverse light activation is a legal safety requirement and a critical visual warning function during reversing maneuvers.

When the reverse light switch fails due to internal contact wear, contamination, or mechanical misalignment, reverse lights may remain off, stay permanently on, or operate intermittently. This creates a serious safety hazard by removing the primary visual warning during reversing and often disables rear assistance systems. Faulty reverse light switches also trigger error codes and electrical system warnings.

Porza supplies high-precision reverse light switches engineered with sealed electrical contacts, exact actuation geometry, and long-cycle durability. Each Porza switch is tested for switching accuracy, vibration resistance, and environmental sealing. With Porza installed, reliable reverse indication, full safety compliance, and proper rear system functionality are restored.
