Hey all, so I'm looking into buying HIDs from VVME, and could someone help me identify the differences between these 4? All 4 of em fit the tb, so idk? http://www.vvme.com/search-result?search_options=1&option_1=12 Thanks.

Just installed my VVME 55W HID's last night and everything is working correctly: high beams and low beams. The question I have is in regards to power: is it necessary to run a secondary power line from the battery with a relay on it? Right now i have them hooked up just through the ballasts...
