Thread: Can I use this 12V AC-DC converter to replace stock headlight for LED?

  1. #1

    Default Can I use this 12V AC-DC converter to replace stock headlight for LED?

    Can I use this 12v AC-DC converter from the link below, on the 12v AC headlight out of my carbed 2017 KTM 300 XC-W, to power a 9-30v DC LED (2.6A draw)?

    Is it possible to do this without touching the startor or stock wiring?

    Nope. You need one that will take up to 36v ac input as the voltage varies as bike revs. I used a 50v diode bridge and a large capacitor. Cam

    But the headlight output isn't already 12v regulated?

    I think the the headlight output is AC. If it is already regulated by the VR to 12V then you could use the convertor. Can you measure the headlight voltage while reving? My bike is the XC which has a slightly different electrical system. Cam.

    It is AC 12v according to KTM manual. I will measure the voltage to be sure.
