Detailed Description

TYC 20-5874-90 is a left headlight assembly built for Buick LeSabre models from 2000 through 2005. The unit uses halogen bulbs for both high and low beam operation and includes the bulbs as part of the complete assembly. With a clear and amber lens, plastic lens material, and plastic housing, this replacement headlamp is configured to match the original exterior lighting layout on the vehicle. The fluted high beam surface supports the beam pattern used in this application, and SAE/DOT compliance helps confirm it meets standard road-use requirements. This part cross-references Buick 19245377 and Partslink GM2502209 for the same application.

Common Issues This Part Can Address

  • Cracked or clouded left headlight lens on a Buick LeSabre
  • Dim or failed halogen headlight output
  • Moisture intrusion or housing damage in the original lamp
  • Reduced nighttime visibility from worn exterior lighting
  • Mismatch between the left headlamp and the rest of the front lighting system

Installation Notes and Tips

Verify left-side fitment before installation and confirm the vehicle is a 2000-2005 Buick LeSabre. Compare the connector, mounting points, and lamp shape to the original assembly before removal. Because this is a complete headlight assembly with bulbs included, transfer and alignment checks should be completed after installation to ensure proper beam aim and road visibility.

Quality Assurance

TYC Regular lighting components are built as replacement assemblies for direct vehicle applications. This headlight assembly is SAE/DOT compliant and is specified for the left side of the Buick LeSabre platform covered by the listed fitment.
