Led Headight Question

Nice idea, fun to think about, but halogen lamps need to use halogen bulbs or they don't work right—period.

The "LED bulbs" now flooding the market are not a legitimate, safe, effective, or legal product. No matter whose name is on them or what the vendor claims, these are a fraudulent scam. They are not capable of producing even a fraction of the amount of light produced by the filament bulb they supposedly replace, let alone producing it in the right pattern for the lamp's optics to work.

Same goes for "HID kits" in halogen-bulb headlamps or fog/auxiliary lamps (any kit, any lamp, any vehicle no matter whether it's a car, truck, motorcycle, etc.). They do not work safely or effectively, which is why they are illegal. See here -- the particulars are different for LED vs. HID, but the principles and problems are the same overall.

There's a ton of junk on the market, but there are also legitimate LED headlamps, good ones that work well, last long, are safe and legal: the 701C from Peterson is good. The Truck-Lite unit is good. The king daddy of them all is the JW Speaker unit in chrome or black. All these are DOT-certified, made in America, and take less power than the original sealed beams so the original wiring is plenty adequate.
