Hi, I hope somebody can help here.
I want to power my rear dynamo light which is an Exposure Red Eye (http://www.exposurelights.com/cycle-lights/accessories/red-eye-long-cable) off a front Dynamo light other than the Exposure Revo. The Exposure Red Eye and Exposure Revo are both designed to work together.
The new front dynamo light output is 9V to the rear light. However the Exposure Red Eye I believe requires less than that. How can I establish the max input voltage and max current requirement of the rear light in order to buy a suitable resistor, if required, to drop the voltage from 9V to whatever it is that the Red Eye requires? At this stage I'm only assuming the voltage needs to be dropped. I think the LED is a Seoul P4 and to be honest I'm not sure whether it's red or white.
This new dynamo light however doesn't have a super capacitor to the rear light so I'll then need to figure out how to provide a standlight to the Red Eye because normally the Revo carries out that function. So what would be the best way of establishing what super capacitor it is that I need to buy? Presumably that's all I'll need i.e. just a resistor and a super capacitor?
