Dude, my local stealership has the regular looking short stalk turnsignals accept they are packed full of led's. They look like LP signals but without a bulb. They are out there and are only going to get more popular. They look like this but are not flush mounts.
I found a guy on ebay that sells the 03-04 gsxr 1000 clear tail lights with the turns intergrated into the tail light and they blink yellow. If that is what you are looking for.. He also sells them for the 600's and the 750's. I am not sure if he has any kind of thing for the older gixxers though.
