Detailed Product Description
This TYC headlight assembly (part number 20-9408-91-9) is engineered to replace the left front headlight on Toyota Avalon vehicles. The assembly features a clear plastic lens with amber detailing to meet vehicle lighting regulations. It incorporates HID technology for the low beam (D4S bulb type) to provide efficient and focused illumination.

The front side marker light bulb is included and uses halogen technology. The housing and lens are both constructed from plastic, ensuring a lightweight yet durable design. This assembly does not include bulbs for the headlight or HID ballast, so bulbs must be sourced separately if needed.
