- Dual-listed part: cataloged under both names, Headlight Relay / Turn Signal Relay, so it is the same component for either callout.
- How it works: an electromagnetically operated switch that uses a low-current control signal to open and close the higher-current lighting circuit.
- Direct fit: a direct-fit replacement for the listed Lexus and Toyota applications.
Signs this relay may need replacing include headlights or turn signals that respond intermittently, fail to come on, or click without switching the load. If a failed relay is the cause of the fault, replacing it with RY-1194 restores the switching function — diagnose the circuit first, since the same symptoms can have other causes.
