I'm sure they are the right type, but now you need to decide if you want 4.3k or 6k bulbs. The K stands for kelvin and is a measure of the colour temperature, 4.3k is factory and is white with a blueish look to it and 6k is a lot more blue. I think 4.3k gives the best light output though, best to ask mkoneman as he changed his to 6k, which is probably what I'd go for if I changed as its a nice blue and not to blue in a chavvy way.
