I have fitted this conversion kit to my HZ van in the H4 bulb ( low/high beams outer light ) http://www.ebay.com.au/itm/H4-HID-Xe...item336fc25825 They are pardon the pun BRILLIANT I also have HID bulbs in the spot lights on the trucks( like daylight all night) 55w Bulbs are three times brighter and half as hot as a 100watt halogen bulb. Shane at Predator Lights is great to deal with!
