DE | First thing before you upgrade bulbs is you need the "all on" mod. So when your high beams are on your low beams are too. Makes a huge difference. If you have fogs too then your really going to put out some light. Although it's illegal to have 6 lights facing forward on at the same time. But this only costs a buck and takes a minute to do.
