The headlight part number for a 2008 Lexus IS 250 isn’t a single universal code; it varies by side and by whether the lamp is halogen or HID. To get the exact OEM number, you must identify the side and lighting option, and then check a VIN-based parts catalog or contact a Lexus dealer.
In this article, we explain why there isn’t one universal number, how to determine the correct part, and the steps to locate the exact OEM code for your vehicle. We also offer guidance on confirming compatibility before ordering a replacement headlight.
What determines the correct headlight part number
Part numbers differ for several reasons. The following factors typically decide the exact code for a 2008 IS 250 headlight:
Side and lighting option
- Left-hand (driver) side vs right-hand (passenger) side
- Halogen vs HID (Bi-Xenon) headlight assemblies
- Mounting brackets, connectors, and beam patterns may differ between sides even if the outer appearance is similar
Because these variables exist, the same vehicle year can have multiple part numbers for headlights.
Market and production revisions
- North American vs international markets often use different part numbers
- Mid-year production changes can introduce updated headlight assemblies with new part codes
Always verify the specific number using the VIN and official catalogs.
How to find the exact part number for your 2008 IS 250
Use a VIN-based lookup and inspect the headlamp housing for the OEM number. The steps below help you confirm the correct code.
- Inspect the back of the installed headlight for a stamped part number, often on a label or embossed on the housing.
- Retrieve the vehicle's VIN and use the official Lexus Parts Catalog or a dealership to search for "Headlamp Assembly" for your year and market.
- Determine whether your headlight is HID or halogen by checking the bulb type or the ballast unit (HID typically uses a ballast and additional wiring).
- Compare the replacement unit's mounting points, connectors, and size to ensure compatibility with your IS 250.
Following these steps will guide you to the exact OEM part number you need. If you share the VIN or market details, I can help you narrow down the precise code.
Common part-number formats and practical notes
For Lexus, headlamp assemblies often carry numbers that indicate the model and side, but the exact digits vary by market and year. Because the 2008 IS 250 spans multiple configurations, there isn’t a single code to memorize. Always verify with official catalogs or a dealer lookup to avoid ordering errors.
Summary
In short, the headlight part number for the 2008 Lexus IS 250 is not universal. The correct number depends on which side you’re replacing, whether the car uses halogen or HID, and market-specific production changes. The most reliable method is to use the VIN to query an official Lexus parts catalog or consult a dealership to obtain the exact OEM part number before purchasing.
