i have the halogens. ebay for 10 dollars, 20 to ship.
i upgraded the wiring myself, because i know how to wire up relays, it's that easy.
i need to aim them down more, but i broke my adjusters, and need to buy new square plastic nut things at 50 cents each. the lights are brighter, but if i did it again, i'd use a hid ballast and xenon bulbs.
