I saw these posted on another forum. Looks like it might be easier to install since they use the same housing, but I don't know if the appropriate resistance is built in. The company seems to imply that they are plug and play. I, myself, ordered Yamaha LED's, for those of you who want to try this option, it is much less cost.
