Well, this is not as clean as some, but they're better than nothing, and are in addition to regular flashers:
5050SMD LED's I've had sitting around for a while. Wired them in (kind of ghetto for now). Grabs attention, which is what I want them to do!
The picture is pretty crappy due to dimlight and cell phone! I can post better pictures at request, but be aware they're held on by zip ties! (cleanly, though).
I also retrofitted my Ninja 250R Integrated tail light for a brighter brake/run/turn. I did both of these because I a blew three turn signal bulbs in 2 weeks.
