I just put these in and there is a tremendous improvement. Some guys will tell you they don't like them but they are certainly brighter. One downside may be that they are a little pricey at $9 a pop. FYI If you purchase, they may give you trouble and you simply need to trim off the wire so that it doesn't wrap around to the back side.

I think chad300tdt has these... someone gave me the idea anyways.
