No. All I ordered was a bulb (D4S). my car already has HIDS factory. The spring retaining clip is part of the oem assembly. Light output is good. Mazda uses OSRAM oems. I got 5500k which are a little more yellow than I expected but the output is very good. https://www.theretrofitsource.com/d...43ztNfWthGEbkiFBVxM5KvpGKM8G0KEBdwxkyK29XrC1I
Thanks for report on bulb replacement... disappointed to hear about the weak design of the bulb retainer. I had hoped this was gonna be one of the easier ones to swap. I need to swap the stock D2S bulbs on my '07 G35x and you have to go through the fender well on that vehicle.
