Bulb connector (left) is only available in bulk from AMP (now owned by Tyco). Wire connector (right) is not a standard type. Every HID kit manufacturer picks their own brand. A customer is more less left up to the HID kit manufacturer for spare parts.
The wire connector (2 pairs of male and female) can be replaced by a different brand alltogether, do a search on "yahoo.com" for "high voltage connector". Minimum voltage specs are 23kVolt.
