Hi, I have a working wired setup for lights using a rear dynamo.
I note 6 volt lights sold for bafang/tsdz2 that are cheap.
I note the hailong battery has a usb power out socket.
Please may i request advice on good light choices (because I am confused).
What I think want to do is fit permanent wired front and rear lights that I plug into the usb port on the battery.
The USB port is a neat idea, and can often supply up to several amps, at 5 volts, sometimes even a tiny tick more!
USB power supplies are generally made short circuit proof in my experience, which is also "cool!"
Identify maximum allowed load, and stay within that, so as to not overheat the USB circuitry and it should work fine for you.
Many e-bikers, due to the low current requirements of LED lighting, simply leave their lights on while riding, even in daylight, to allow them to "be seen" better by other road users.
I personally never, ever rely just on lighting, supplied from an e-bike's battery, and I always have extra lights with an internal (usually rechargeable) batteries as well, front and back!
Just for if the bike battery gets fully discharged while riding at night, then it shuts down power to the lights and motor, as many actually do!
Very disconcerting! But safer for the expensive battery!
A thought, some modern bike lights have a USB port (my under the seat rear light/alarm for example), to charge the light's internal battery, so a cheap USB 2.0 charging cable (from ebay), could maintain the charge in the light's own battery, but still allow several hours at least, of lighting even after the bike battery has shut down!
Safety first!
regards and I hope these thoughts are helpful!!
