Hi, I am planning on getting some HID's for my headlights and want to do both high and low beam now the low beams will not present a problem as they are a direct fit. The high beams will be a issue as currently they are H1R1 bulb and standard HB3 wont lock into place. reading a older thread here: http://au.toyotaownersclub.com/forums/topic/24130-xenon-bulb-upgrade-07-sx6/ It states by DJKOR that some modification is needed. what do i need to do to make them fit looking at some hb3 halogens i have here i can't seem to work out if its the thickness or legenth? Someone who has do this upgrade co
