Follow that link.... Use THIS link to find out the bulb size you need... Install is easy, just need to find a good place to mount the converter box... Also you have a projector headlight assembly as most cars above the 30k price range offer... So you'll be okay, as they will direct the light in the right direction and won't make people hate you... As far as Kelvin goes.. I went for the one in the 5K range and it is white... Wish I went for the 4K since at certain weather conditions I notice a drop off in lighting... Get the 55w kit as it is stronger for the low beam setup.... GL!
