Detailed Description

The Standard Ignition LSH123 is a headlight level sensor used in the front right position on 2010-2013 Lexus RX350 and 2010-2013 Lexus RX450h models. This sensor helps the vehicle’s lighting system read suspension position so headlamp aim can respond correctly to changing load and ride height. If you are searching for a Lexus RX350 front right headlight level sensor or a Lexus RX450h front right headlight level sensor, LSH123 is the direct-fit reference to check.

This part cross-references 8940548010 and HLS558 for the same application.

What It Helps Address

  • Headlights that do not level correctly
  • Incorrect beam aim after suspension movement
  • Sensor-related leveling warning or fault conditions
  • Uneven lighting response on the front right side
  • Replacement needs for a worn or failed ride-height sensor

Installation Notes and Tips

Verify the connector type and mounting location before installation. Confirm the front right position and match the part number to the original sensor on the vehicle. After installation, inspect headlamp aim and clear any stored lighting or chassis-related fault codes if required by the vehicle system.

Quality Assurance

Standard Ignition supplies replacement electrical components for OE-style service applications. LSH123 is identified for the listed Lexus RX350 and RX450h fitments and should be matched to the vehicle’s original sensor configuration before installation.
