    BBSHD headlamp cable?

    I just recently built my fist E-Bike and am loving it. I purchased a BBSHD, gear sensor, color display, aluminum chain ring and a twist throttle from Luna Cycle. The build went in fairly easy but I have 1000 questions so I'm aesthetic I found this forum with so many like minded and cool people. I'll start with this one. Does anyone know where to purchase and how to install a headlamp cable for the BBSHD. Sec 3.4 of the BBSHD manual talks about a optional headlamp cable and sec 7.4 of the DPC 14 manual talks about when holding down the up button for 1 second should turn the headlamp on/off along with the night screen. I contacted Luna Cycle and they said they don't carry a headlamp cable and they just splice the headlamp into the battery cable. I could do this but it would be really sweet if the headlamp was integrated with the BBSHD and color display. Also any suggestions on a sleek headlamp that could be mounted on the front of the forks would be greatly appreciated. Thanks in advance for your help.

    excuse the ugly lead acid batteries on the back. I'm in the process of purchasing a 52v Lithium pack.

    Bafang tends to publish things before implementing. If you read their description of the color display and actually look at the setup in the display there's a number of options that were not integrated. The USB port can support a headlamp but not much at 5V. IMO most headlamps other than the German standard are problematic in traffic. Baffin builds great stuff, but tend to be poor communicators. Thank goodness for Luna!

      That does, Thanks for clarifying. I knew their was a reason it wasn't mentioned anywhere else. Luna has been great in this journey. I don't think I'd have been able to build this bike without them. Another question if you don't mind. These lights that are rechargeable from a USB should be ideal to run from that port? and is that port active all the time?

        I bought a rather espensive usb chargeablr headlamp thinking it would run off the usp port from the dashboard. Wrong. It will charge from the port but it will not light while it is charging. I am a bit bummed.

          Shawn Graham The USB on the color display is live as long as the unit is operating. The screen doesn't have to be on but it needs to be "running". The limits of the port are a modest 500mA (½ an amp) which is USB minimum. SOME lights can accept a charge and operate simultaneously but not all, that's a function decided by the light mfg not Bafang. B&M (Busch& Meuller) lights are usually good about that since they are designed to run from a genhub.

            I either learn things the hard way or the expensive way. I do like how bright this $100+ bontrager light is but I just assumed it would light while charging. Will be hard pressed to buy a new one. My lbs does seem to have a 30 day - no happy/return - but I hate invoking that. Still........I am going to check out b and m right now. I bought the bont after getting tired of shopping.

              Another option is buy a DC-DC converter . I have one. But you will need a soldering iron to solder on cables . This is a good investment for any DYI ebiker. It reduces the voltage down from 60 volt to 12 volt.

                So that you are now running a 12 volt headlight?

                  Yes. This is what I have. But as I said you will need to soldier wires onto the converter. You will also need to purchase more XT90s, 12 gauge wire and smaller 28 gauge going from the converter to the lights. You will need to make a parallel adaptor from the battery with one of the 2 paralleled cables going to the motor and the other running to the DCDC converter. I will post up some pictures.

                    If you have the 6V light output wire the lights are LIGHT-6V-F and LIGHT-6V-R

                      There are some rumours that this headlight cable is only capable of about 0.5A at 6V, is there any confirmation? This seems really strange as it means it is useless - any headlamp that gives at least some light uses more than 0.5A. Any confirmation of this restriction? I successfully plugged the 8W headlamp (supernova M99) plus a tail lamp (probably another 2W) and they worked fine. But I am afraid of running them as such significant over-use of the plug can cause the problem with the controller if it really has the 0.5A restriction.

                        I kept hooking random lights on mine with no success til it finally died. Still starts and drives thankfully.

                          I bought this: https://www.lupine.de/products/bike-...specifications but the light keeps blinking when connected to the dedicated light cable, like it doesn't get enough power from the motor cable, is it normal?

                            The manual is oddly wrong about the headlight plug. They showed a barrel plug while it is actually a 2 pin JST type female plug is what's used for my headlight out from my BBSHD. Mine outputted 6.2 volts VNL. I believe the manual's rating of 6 volt 500 mA rating which isn't enough for any useful light output. I purchased a Solid State relay http://a.co/2Jbdfnd that can use anything between 3 - 32 VDC and switches on power. I then purchased this headlamp http://a.co/cvfrE51 that works on any volt from 12 - 80 VDC. When I hold the up button on my 850C it activates the Relay which turns connects the circuit of my headlight that is directly wired to my battery.

                            A solid state relay is not necessary at all but I chose it due to it's small size. I soldered directly to the Relay's pins.
