I don't know if you're looking for a replacement that is exactly the same as the ones you're taking off, if so, I am not sure where to guide you. If you are looking for something a bit different, as I am you should be able to find them at just about any large motorcycle store online, do a google search or two. One place that is in my area, and has a pretty good online source is http://www.performancecycle.com . They have a few neat clear turn signals, although not specifically for the Versys.
Try http://clearalternatives.com/ they make them for multiple different bikes. I haven't looked around their site but I'd think they'd carry them as they are the same as the ones used on many of the Kawasaki's now.
