I found my turn signal kit at http://www.bmikarts.com
(USA) for just $25 us. Part number Hd6v. It includes all metal chrome plated front/rear lights, flasher unit, and handlebar switch, and comes with 6v components. Very pleased with the quality. I used the rear license plate holes to mount the supplied brackets on my SQ 4 MK II. Looks like it could have come from the factory! I haven't yet decided how/where to mount front signals.
