LED Headlights

[Spiderwatts_imp]

I just received the new issue of Hot Bike, I know it’s mainly HD bikes, but I’ve owned a few HD’s and it’s a nice reading magazine with some nice scenery with female models too.
Anyway, Drag Specialties advertises quite a few LED headlight assemblies, all round light shells and they appear to have a nice shell to enhance the LED bulbs with proper use of reflector and LED bulb. Not sure if they are plug and play or if a regulator is needed because of compatibility with lighting. But I wonder if they could be used on our pre ‘17 non LED headlight bikes with some minor mods to headlight shell and little to no wire cutting.
Are there any lighting experts here with any advice or experience with these or other aftermarket LED headlights we could get for our bikes?
I would guess a lot of us would be interested in this upgrade. It would still look stock, hopefully add some brighter and longer reaching light, and reduce heat and battery drain.
Just an idea. It looks like most of new bikes are headed towards LED headlights.
