Re: Headlights

A 60V mod will bring them to the right voltage, but may possibly undo regenerative braking (if you have that on the bike), and reduce controller lifetime (if not immediately blow the controller caps).

The problem is that the bulbs are made for cars, which alternator usually gets a fluxuating voltage of around 13,8-14V. A car battery does not provide this much voltage, but will need it to charge.
So there's no real solution. You could wire a couple of strings of 4 LED's in series, and use them as brake lights, and blinkers, but the headlights are hard to fix.

Re: Headlights

Thank you for the reply.

I'm thinking of adding a good bicycle light {one that has its own rechargeable battery} to the front of the xb-610 utilizing the screw above the headlight.

How do an increase in voltage change head light voltage?

A 60V mod will bring them to the right voltage, but may possibly undo regenerative braking (if you have that on the bike), and reduce controller lifetime (if not immediately blow the controller caps).
Isn't there a DC-DC converter in a XM-600?
Whether you place 36 volt or 72 volt on a converter it still makes 12 volt to lights and controller. Some DC-DC converters make 14.0 volts and some others make 13.2 but the eXtreme converters make 11.5 volts.

Not really. The voltage convertor is just a downgrader. It lowers the voltage, but does not stabilize it.
It's dependent on input voltage. Some peoples have tried it, and told that it works.
