What you are referring to is the "Bi-Xenon" headlight assembly. Certain vehicles have the Bi-Xenon headlight assembly that uses a set of HID bulbs (2 Bulbs) for both high and low beams. Basically, it is the function of the headlight assembly that opens up the solenoid in the headlight for a full beam when the driver turns on the high beams and closes when driving in the low beams. D3S is the correct size for the 2015 Audi A3 equipped with HID Xenon headlights. Same year trim also had the halogen headlight model. If this is the case, the correct halogen size is H7. Yes, this is the right bulb for your 2010 A5 as long as your Audi came with HID light system from factory. Now, HID voltage is 85V and halogen H7 is 12V.
