There is a group buy going on for watsen design LED signals. They are expensive, but we are getting a group discount thanks to Coskie's efforts. Your 04 would take the WD114 series in whatever color you see on the list Yamaha LED Signals . The WDN129 series could be used for the back (with many fender eliminators) as the stud used is only 4mm. These are plug-n-play in the front - not sure for the rear - when you get the running lights option. I personally like that, because it makes it just like factory functionality. These are lifetime warranty - last ones you would ever have to buy for the bike. Roger, the guy who makes them there, seems pretty nice. He is doing the deal for us as a one time shot. I am getting two sets for around 210.00. Hope this gives you some info to consider.:Flash:
