You'd typically swap out the 9006 low beam bulbs. You usually don't keep your high beams on for extended amounts of time and they're constantly being turned on and off. You don't want to turn on and off your ballasts constantly as it'd put a considerable amount of wear on them.isleepinadrawer said:im thinking of possibly installing some HID
in the oem headlights, are there 2 bulbs? one for high beam and one for low?
which one do you guys swap out with hids?
