I've got that setup on my VF. HID low and high and a dual colour lightbar behind the lower grill. The Lightbar is not great, but certainly lights up the peripherals well before the high beams warm up. 95% of my 200km round trip to work daily is 80kph - 110kph non suburban, so it's pretty essential when driving at dusk or after most nights. In the HSV, I have HID low and high and halogen driving lights to get the light up quickly when I need high beams.
