The low and high beams use different bulbs (H11 and 9005), so buy both if you are replacing the pair. All halogen/incandescent.. Factory LED units are sealed and are not a bulb you can swap. Fog lights take a 9006 bulb, which is a separate size from the headlights. Note that sizes can vary by trim (2004 facelift Gen1. Low beam to H11.), so check your existing bulb if your car is optioned differently.
