Mazda Owners: Because of the way the original halogen bulb clips into the housing in some applications, an HID bulb won't be a direct swap without these adapters.
Recommended: Check your headlights for a similar looking plastic part socket behind the bulb to identify whether or not you need these. All housings would take H7 bulbs, the original part extends the +/- connector towards the electrical socket
Take Note: Unfortunately, Morimoto's larger base design does not allow them to work with these adapters without modification. If you're doing an HID upgrade on a euro that requires these adapters, we urge you to pick up a different set of H7 HID bulbs that are hard-wired to make your life a little easier.
By Design: Slotted design allows the wiring for the bulb to slide in from the side, and then original clip assembly will hold bulb firmly in place just like stock.
FITMENT NOTE: These are not compatible with the Morimoto XB HID bulbs, unfortunately.
