March 30, 2009, 11:53:35 PMI ordered the indicator lights from Hitchcocks along with a group of other parts that our host doesn't carry. They can, of course, be obtained in the states if you know where to look, but they were cheap from Hitchcocks so I saved myself the bother of searching locally.
As for the installation, they are a press fit into the holes you must drill to accommodate them, and you use the existing wiring from the lights in the original speedo. (I also had to drill holes in both fenders to install the license plates.)
They are an immense improvement over the wimpy stock lights, but again, you must be willing to drill holes of the correct diameter in the casquette while making sure you drill the holes "above" the existing side holes that the brake and throttle cables feed through or you'll have interference problems.
