Detailed Description

Standard Ignition LSH112 is a headlight level sensor used in vehicles equipped with automatic headlamp leveling. By reporting rear suspension height changes, the sensor helps the lighting system adjust beam aim as vehicle load and road conditions change. This part is a direct-fit electrical sensor with a plug-in connector type and is listed for rear right installation on the Lexus ES330 and Lexus ES300. This part cross-references Hella (e.g., HLS525) for the same application.

What It Helps Address

• Headlights pointing too high or too low
• Warning lights related to headlamp leveling input
• Inconsistent beam aim after suspension movement
• Faulty sensor signal from rear ride-height monitoring
• Loss of automatic headlight leveling function

Installation Notes and Tips

Verify the rear right mounting location and connector style before installation. Inspect the linkage, wiring, and mounting points for wear or corrosion, since sensor faults can be caused by damaged connections or suspension-related movement. Confirm vehicle application by year, make, model, and position before ordering.

Quality Assurance

Standard Ignition replacement sensors are built for OE-style fitment and electrical connection on the listed applications. Confirmed fitment includes 2004-2006 Lexus ES330, rear right, and 2002-2003 Lexus ES300, rear right.
