These came with my RD400c, but obviously don't fit up (I already have a good working set. The face diameter is ~75mm and the bracket has 80mm mounting hole spacing. Wires from them are: 2 greens, black, brown, blue, and light green with red stripe in one bundle and a green and a brown in the other bundle. The light green/red has a female bullet connector, all others are male bullet. No labling other than the Nippon Seiki branding. Both seem to work fine (tested with my battery drill).
The gray sheathing says perhaps early XS. But that redline seems two stroke.
plastic lenses... I'd guess small suzuki
looks like some of my old honda stuff
