	This particular DR6 Green Arrow did teh job of a single component, a light bulb, with a mere 106 discrete components, 44 of them being actual green LEDs, along with a PCB weather tight case and fasteners. Green LED's are actually arannged as groups of 4 in parallel, wired 11 times in series.

	Under the hood there is quite a bit of circuitry given that this is a "dumb light" controlled externally by being flipped on and off. This is at the least a complex constant current supply with a fairly high power factor. Later models include compensation for continuous brightness after years of use and environmental monitoring and compensation features.
