I wonder if anyone can answer me a question ? the loom on this controller has an output for control of lights or light as my battery is 48volt which actually measure 54 volts off load , I wondered what the output voltage is at the light terminal. So I stuck my voltmeter in it on DC and nothing but flashed a voltage on disconnecting the leads .As it was -2 deg outside I came back in , decided I would ask on the forum first .I also noticed a company selling one e-bay called WUXING 36V LED Front Light .Further investigation showed that this light is 36/48 volt , next question can the 36 volt be used at 54 volts .I will probably never use lights on my bike but I hate loose plugs ,and want to plug them into something .
