Has anyone here successfully used one of these on this model bike and know which part number they used? I ordered a 20W-DZ for the GT and now I get a "brake failure" indicator on the dash. I suspect I ordered the wrong part number although it might make a difference that the bike also a set of Hyper-Lites (flashing LEDs on either side of the license plate). If others here have used the 20W-DZ then I would conclude that having the Kisan *and* the Hyper-Lite is too much for the bike's lamp-check function to tolerate.

I'll probably call Kisan this week and see what they say. They'll probably tell me I'm an idiot and ordered the wrong part.

Thanks for your advice and comments.
