The low and high beams use different bulbs (9006 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 (Pre-facelift Gen1. Low beam 9006/HB4. Front turn amber 3457.), so check your existing bulb if your car is optioned differently.
