42V/36V to 12V step down for headlights?

Does anyone have a good idea how to get the 12V for headlights or similar things? Does a 36V stepDown module works on 42V full charged battery? Who got experience with that?

I think Hobbyking might have what you’re looking for.

I have some lights on my board powered form the 10s battery.

I have such a step down converter with red pcb. Those with red pcb are better… https://www.ebay.com/p/Dc-dc-5v-12v-24v-48v-Buck-Adjustable-Step-Down-Voltage-Converter-Module-Car-COI/22018628241

This is the same that @thisguyhere posted (I think) but a little bit cheaper
