If you use an HID retrofit kit, the low and high beams are one unit. The high beam is controlled by a deflector in the projector and the second light is moot. Utilizing the high beam connector on your car is what controls the deflector. A projector will not fit with two bulbs. My type D have two bulbs but the lower bulb that used to operate on the JDM is a low output daytime light I believe. I don't use it and that portion is blacked out like the rest of the reflector.
