Please check the globe fitted to your vehicle before ordering. Even if our catalogue or vehicle compatibility table shows this globe suits your vehicle, we strongly recommend confirming it against the globe currently fitted to your car. In our experience the catalogues are reliable, but a single vehicle can use several different globe types depending on the position — for example Low Beam, High Beam or Fog Light — and these details often can't be listed in the catalogue. The only certain way to get the right globe is to check what is physically in the vehicle. Please don't rely on the Parts Catalogue or Vehicle Compatibility table alone.

Packaging: Manufacturers periodically update their packaging and labelling. You may receive the current or a previous design — the product, formulation and part number are unchanged.
Fitment (vehicle-specific products): For products listed to suit a specific vehicle, our fitment data is kept as accurate as possible, but vehicle catalogues are not perfect. Some models had more than one part fitted depending on build date, engine, or component size/variant. It is the buyer's responsibility to confirm the part suits their vehicle before purchasing. If you have any doubt, please message us with your vehicle's registration number and state (preferred), or full VIN/build details, and we'll do our best to confirm before you buy.
