HID's are yesterday's tech, check out OPT7 LED headlights. Retrofit source shows there 6K HID kit produces 3200 lumins of light where the OPT7 6K LED kits produces 3500 lumins of light so the LED's are brighter. The Retrofit Source sells their kits for around $150, OPT7 sells their headlight kits for $100 so the LED's cost less.
Brighter light, no shadow from the ground wire, costs less, no warm up time so perfect for high beams too, no relay wire harness needed, straight plug and play, you can keep the DRL's, makes me wonder why anyone would bother with HID anymore.
