LED headlamp replacement for H6014 7" round

My 1980 KZ750 LTD has the stock semi sealed h6014 headlamp fixture with a H4 halogen bulb. I've been looking at the 7" LED bulbs by Truck-Lite, GE and others. Will any of these fit this bike plug and play? I have asked tech questions to the manufacturers and they give gray responses like it should fit or it is a direct replacement for.....I just want to know before I order something and wind up with the hassle and expense of a return. Any firsthand help is appreciated.

LCD = Liquid crystal display
LED = Light emitting diode

LED headlights look very interesting, more light and less power used. There are lots of led h4 replacements on the market, some are very inexpensive. I have one I'm going to try in my 750 twin.
