That is definitely it, same weird pattern on the black box. I don't why they don't have 3 boxes, one for the chain stay, one for the seat stay and one that juts out from the axle. It would only slightly increase resistance but would (with 3 proper coils) generate a lot of voltage which could be stepped down and give 3x the power. 1 watt split between front and rear lights is great for visibility but wouldn't give much in terms of seeing the road.

Thank you, much obliged.

This is the same system, but the person who had it had an optional computer. I traced the wire from the computer mount to the generator box. I guess they have it with a computer option.
