I got a good deal on a Trail Tech indicator light panel for the Vapor Speedo/Tach. Since the Kawasaki indicator light sockets plug right in, I was able to simply use the stock wiring harness, sockets and bulbs, for a five-minute installation. Here it is:
It's mounted by sliding the bracket under the steering lock housing cover, then drilling it and securing it with two small stainless steel bolts (from a computer chassis, but not yet installed in this photo). Then, after looking at the result, I realized I could have mounted it directly to the headlight bucket with 1" spacers, and run the wires through a hole.
