Headlight prices for the ML350 vary widely, but you can expect roughly $150 to $2,000 per headlight depending on year, technology, and supplier.
Understanding ML350 generations and headlight options
The ML350 has appeared across multiple M-Class generations, each with different front-light configurations. Depending on the year, headlights can range from simpler halogen units to advanced HID projector assemblies or LED modules, with some models offering adaptive lighting and auto-leveling.
Key factors that influence price
The main elements that affect price are:
- Model year and generation (older ML350s use simpler halogen assemblies; newer models may use HID or LED)
- Headlight technology (halogen vs HID projector vs LED modules)
- Left vs right side and presence of adaptive or auto-leveling systems
- OEM vs aftermarket (OEM new units generally cost more)
- Condition (new vs used/refurbished) and warranty options
Understanding these factors helps buyers set expectations and narrow options quickly.

Where to shop and how to verify compatibility
To avoid mismatches and ensure proper fit, verify compatibility using your ML350’s VIN and the exact headlight part number. Compare listings from multiple sources and check return policies and warranties. Here are common purchase channels.
- Mercedes-Benz dealerships and official parts portals
- Certified aftermarket retailers and lighting specialists
- General auto parts retailers (e.g., AutoZone, RockAuto) and online marketplaces
- Salvage yards and used-car parts dealers (for lower prices, with risk)
Always confirm that the seller guarantees fitment and that the ballast, connectors, and wiring are compatible with your vehicle’s electrical system.
Summary

Expect roughly $150–$350 for aftermarket halogen units, $300–$600 for aftermarket HID, and $500–$2,200 for LED/OEM variants, with used options often cheaper but with higher risk. Always verify compatibility with your vehicle’s VIN and consider total costs including installation, taxes, and potential ballast replacements. By shopping across dealers, aftermarket suppliers, and salvage yards, you can find a solution that fits your budget and your ML350’s needs.
