Ford 1910 Light Bulb LED Sub

[sruman]

Team,
I'm looking to replace the lightbulbs in a Ford model 1910 tractor. Current bulbs are incandescent 12V35/35WS and I'd like to upgrade to LED style. Any conversions bulbs known, or a website that I could begin to research. I've googled a few times, but nothing appears to be available.
Any help would be appreciated.

Thanks everyone.
