The H8 and H9 share the same physical base and socket type, which means you can use either one in a housing designed for the other. However, there may be slight differences in rated wattage or light output between the two. For the best results, use the specific bulb type listed in your vehicle's owner's manual. If your manual specifies H8 but you can only find H9, it will fit and work safely. When upgrading to LED, look for a kit that lists both H8 and H9 compatibility.
