I changed my fogs and headlights to led using the ODX brand.The fogs are 9006 and the headlights are 9005 projector.The ODX lights have a solid lifetime warranty and they are one of a very few companies that sell specific bulbs for projector headlights.The projector headlights DO take a Projector bulb which they are designed to do.I did try several regular led bulbs from Amazon and they were a waste of time as the beam from them was scattered meaning dark and light spots in the beam in front of you.and no very efficient.Both the fog and the headlight bulbs from ODX are some of the very best on the market.They call their headlight bulbs PROJEKTOR.The difference in a projector bulds is that they have only one led panel which reflects light off of the top half of the lens.When you activate the high beams a small shudder opens and lets light reflect off of the entire perimeter of the lens.Imagine a two or 4 sided led panelled led bulb trying to reflect light off of a single reflector on the top half of the projector would look like,completely scattered.Most of the Amazon bulbs are designed for the reflector beam headlight buckets.I live in Canada and the prices I paid were 100.00 for the fogs and 170.00 for the headlights but they are well worth it compared to the Amazon crap.Look them up on youtube and they will show you a comparison video.FYI the stock halogens,I found threw a better beam than the amazon leds but not as white.Also a very important note is the the ODX lights are specifically designed not to blind oncoming traffic as I have never been flashed even once.To each his own but given the accurate info I provided you,It's your choice.By the way I do not work for ODX,LOL.
