used polit hid bulbs. used time about 100 hrs. about 6 month. i dont drive at night very often so they are fairly new. just upgraded to hid headlights no need for this any more. works on your fogs and headlight. not some cheap ebay bulbs. wire is very thick and longer than the ebay bulbs. these bulbs cost 90 dollars a pair when buying new. i am asking 25 dollars shipped or 20 dollars pick up in the bay area.
