Ultra White Signal Bulbs

I've been looking for some ultra white signal bulbs for my 1992 accord but don't know who's are really ultra white. I saw some at auto zone that were ultra white and I forgot how many watts they were, but they had some funny looking wire connections. I want the ones that are extremely bright. I found some at this website called www.Lightlens.com and they are 12V 5W but I don't know if those are the right ones. Can somebody tell me where I can get those kind of bulbsor if they are the right ones. Thanks.
