Basic spotlight kit is simply these four parts. It is a "static" kit and does not come with anything to make it "lights up". With some modification by the end user it can be made to accept an LED and wiring. The one shown on my M60 above has a mirrored plastic refractor which I cut out and made to fit in place of the supplied flat part (bottom left in photo) intended to be painted silver and used as the refractor/lens cut out template.
