i forget the name brand i bought, but all you need is the bulbs. you do not need to chacnge out the rings. very easy.. but you will have to take the bumper cover off to get to them, especially the passenger side. there is a DIY picture slides that someone has added in doing so. i used it, and it was very helpful. had to take my bumper cover off twice now, and i can do it less than 15 minutes.. 5W white is a good choice, i went blue, and wish i had went white.. youll need, nut driver, hex set, and a flat and phillips head screw driver. and thats about it..
