Keep the right circuit switching on cue with the Standard Ignition Anti-Theft Relay / Headlight Relay RY-636. It installs as a direct-fit replacement for the 2003-2004 Hyundai Elantra, 1999-2005 Hyundai Sonata, 2001 Hyundai XG300 and 2002-2005 Hyundai XG350.
This part is cataloged under two names — Anti-Theft Relay and Headlight Relay — so it may be listed either way for your vehicle.
- Electromechanical switching: uses a low-current control signal to open and close a higher-current circuit.
- Dual application: serves the anti-theft and headlight circuits on the listed Hyundai models.
- Direct replacement: designed to install in place of the original relay on the listed applications.
Signs the relay may need replacing include intermittent or no operation of the circuit it controls, or a relay that clicks but fails to power the load. Because these symptoms can also stem from wiring, fuses, or switches, diagnose the cause before replacing. If a failed relay is the cause of the fault, this unit replaces it.
