Three checks before you buy.

01

Check the original bulb code

Read the code on your existing bulb or check the vehicle handbook. This product is listed with a D1S fitting.

02

Identify the headlamp version

Confirm the required light position and whether the vehicle has halogen, HID/xenon or factory LED headlights. The same model can have different headlamp options.

03

Compare the complete installation

For this LED replacement, confirm clearance, connectors and compatibility with the existing lighting system. A matching fitting code alone does not confirm a conversion.

Check the bulb fitting, available clearance, headlight system and intended use before ordering. Contact us with your vehicle details if unsure. For off-road / motorsport use only. Road-use approval for this LED replacement has not been verified. A matching bulb fitting, CE marking or CANbus compatibility does not establish road approval. Ask us to confirm the exact application if you are unsure.
