49v to 12v reducer
 

Hello everyone, I have a rad power bike with a 48 volt system and I'm wondering if there is a way that I can reduce the voltage from the headlight wires to 12 volts in order to upgrade to a high lumen, hardwired light that I already have from a previous bike.

Yeah I've done this, for lighting and a car horn.

You need a stepdown convertor, little sealed unit the size of a matchbox, cost me a tenner new off eBay.
