Well, aside from the integrated taillight, I've also seen a clear one for a more modern look, but it's pretty pricey ($80 I think it was). There are a ton of modern looking LED turn signals on ebay though. I just chose to change the bulbs because I had trouble finding one that wasn't "too modern" looking. I didn't think they looked right with the 955s older, swoopier looking bodywork. But, obviously that's subjective and only my opinion. Brighter was my goal. It made a big difference in my previous bike as far as how many people were coming close to rear ending me so I figured it would help the Sprint as well.
I do admit I like the clear turn signals on the 1050 better, but one thing about rear signals is you don't have to see them when you're riding
But, check ebay as I'm sure you will find something that you like, and probably for less than $20, too.
