Have seen a lot of people opt for different turn signals, much like they'd do with different headlamps or whatever the case may be. These do look interesting but I would really like to see it installed on the bike completely to make a judgement on it. Looks pretty good from here though, but I would have liked those screws in it to be black screws instead to blend better.
I wouldn't say funny, with anything enthusiast related, it's just what to expect. Some people feel the need to change it and think those look much better, others think you just shouldn't change things like that as it'll take away from the bike. Different flavors for everyone.
Single light assemblies are cleaner looking, but then you have drivers who are used to the traditional lights and could very well run you over because they didn't see the more stealthy signals. IMO, its more for safety than anything and people are inattentive enough as is.
With how universal most signal lights are when it come to mounting, the options for adding an aftermarket set to your scr950 are pretty much endless. Though some would go with the bike's styling better than others.
Anything in the rear end is relatively simple and you're imagination to go much crazy than trying to do a headlight retrofit type of ordeal. At least for me. I do prefer the stealthy look though and maintaining a sleek sort of feel.
