Mercedes W204 Headlamp Bulbs and Fitment Checks

W204 lighting varies by generation and headlamp assembly. Confirm the lamp marking and vehicle details before selecting a bulb or complete unit.

A Mercedes W204 headlamp query can refer to a replacement bulb, a complete headlight assembly or an LED conversion. Those are different purchases. The correct choice depends on the car's production version and the fitted lamp, so identify the headlight approval number and the required beam function before comparing parts.

Common questions

Questions before you buy

How do I find the right headlamp bulb for a Mercedes W204?

Identify the car's year and headlamp type, then check the bulb specification in the handbook or vehicle lamp finder. Compare the headlight approval marking with the manufacturer's compatibility list before ordering.

Do all Mercedes W204 models use the same headlamp bulb?

No single bulb should be assumed for every W204. Body style, year, headlamp assembly and beam function can affect the required part, so verify the specific vehicle and lamp.

Can I fit an LED replacement bulb to a W204?

Only if the exact bulb and headlamp approval combination is listed as compatible and permitted for road use. Check the current manufacturer's vehicle-specific list and applicable UK requirements.

Where is the headlamp approval number on a W204?

It is marked on the headlamp lens or housing, though its position can vary by assembly. If it is difficult to read, consult the vehicle handbook or a qualified garage rather than choosing by model name alone.
