I notice the Supernova E3 Pro 2 can be had for £65 with 'no rear wire' or for £140
Remarkable difference! I imagine that if the light has that much difference in price, it may be that the light just doesn't have the circuitry/terminals to feed a rear light.
Yeah, although hard to imagine that much circuitry required. I went for a B&M IQ-X (£100) combined with the Toplight rear light. Haven't had a chance put it through its paces on unlit roads but seems to be working great. SP-9 dynamo rolls along nicely.
Let me know how you find the IQ-X I'm this close to getting one.
The Supernova rear lights take DC (most others take AC) so it has rectification circuitry in the light. If you were running an AC rear then you could just run the front and rear in parallel.
