2005 TE450 LED Headlight Advice

Hello,

Rebuilding my 2005 TE450, and have a Baja Designs Squadron Sport headlight I'd like to use. Looking for advice on how to best wiring it in (and keep it as simple as possible).

• BD Headlight is rated at 26w/2amps
• Bike electrics/harness are bare minimum. No key. Start and Kill switch. Acerbis LED tail/brake run off AC.
• My understanding is that the stator output is 100w AC / 30w DC (or there about).

I'd like to keep the light on the AC circuit, and not have to wire in a switch. Also think putting in a AC to DC converter for the headlight would help it last and remove the flicker. However, that's as far as my "knowledge" goes.
Is using an AD to DC converter that possible? If so, any recommendations?
Or should I just wire it to DC/Battery using a switch?
Fuse? Relay?
Thanks in advance for any advice.

Possible, Yes.
I was planning to use what's called a buck converter. search "AC/DC to DC Buck Step Down Volt Converter 3.3V 5V 9V 12V 24V 6A Rectifier Filter" in ebay. Less than $10 shipped and should be good for double what you need power wise. Just need to build a custom enclosure to protect the circuit board. Circuit protection is always a good idea; not much provision provided with the stock loom, so you'll be on your own for that portion.

The crappy part is BD has a version of the Squadron that can run off of AC, but they will not sell the module separately...

Cyclops sells an AC to DC rectifier to use with their LED replacement blubs that will also work if custom is not your cup of tea.
