Bought two B&M Lumotec OvalSenso (one of them is the Plus version with standlight) lamps, to go with my Schmidt hub generator.
Both work perfectly fine when connected to the generator one at a time. But when I connect them in series, they don't light up at all. Not the tiniest flicker. Nothing! Also, the wheel spins the same way it does when there is no closed circuit - quite different from when there is a complete circuit.
What is wrong?
I've connected the wires like this (although not as neat, at least not yet):
Both lamps are in the ON position - not sensor or off.
They're electrically isolated from each other, apart from the wiring, of course.
I'm really confused right now! Help!
