These threads offer some thoughts on upgrading lighting powered by the bike's lighting circuit;Hi,
not sure if you guys found an answer but I was also looking for an upgrade. Still haven't found a proper replacement but took a multimeter testing on the leads to the Kendo+ and the voltage is much higher than what a Lezyne ebike macro 1000 allows. If changing the controller voltage isn't the solution than matching the output should be an easier job. Please share if you found an alternative.

Wired-In Ebike Lights Guide
While visiting my buddy Chris Nolte at Propel Bikes in Brooklyn, NY we spent some time talking about bicycle lights. Chris runs an electric bike shop, so most of the models we looked at had the option to wire-in some lights to run off of the ebike battery. Some of these lights would work just...electricbikereview.com
Jugernaut Ultra 1000 - Dutch commuter style w/ integrated lights
Just finished re-configuring my new Jugernaut Ultra 1000 in "commuter mode" complete with integrated 48V front and rear lighting! Before I get to the integrated lights (because that's it's own story) here are the changes I made to the stock configuration: Busch + Müller IQ X E headlight (150...electricbikereview.com
One of the concerns is the output current of the ebike's lighting circuit vs the requirements of any upgraded light. Compatibility charts have been published over the years. Lyzne offers the attached chart.
If you can't find your motor on one of these charts, try getting the spec from the manufacturer then match it to your light. It's always best to have a factor of safety so try not to upgrade to a light that pushes the manufacturer's spec to the limit.
Good luck.
I did the same technique for my DIY ebike. Used a DC-to-DC converter to run a 12V light off the bike's 48v battery pack. Worked for years, until I retired that bike.***********
@Sierratim - Amazing! Thank you so much! This is precious. I'll spend sometime reading these

Edit: the Jugernaut Ultra 1000 solution of using a relay switch is great for under powered light leads. In my case it's the oposite so I'm thinking of going with an isolated dc-dc converter to drop from 36v to 12v and gain up to 3Amps!
Our area has very steep hills. Our DIY ebikes had 48V 20Ah battery packs. With motors that drew up to 1Kw I honestly didn't notice any change in range when I added the lights. We used them in flash mode for day rides as well as at max brightness for evening rides. Got the same miles per charge either way.Cool, good to confirm it works well and it worked for years on your bike! Yes, I was looking at the Supernova V1260 yesterday and it is not only expensive but also not half the fun of engineering it myself.
BTW, how was battery life affected by the converter and new light?
