High voltage headlight

Cos they are 110 volt ac and your battery is 96 volts dc.
 
Can you post a picture or a link to the 110v dc led flood light?
 
DC voltage is DC voltage. If you motorcycle can produce enough DC voltage to make the bulb glow, it will glow. (provided the bulb runs on DC.) Under volting it will not give it it's brightest illumination.

Other considerations:

It is not made for vibrations
It is not made to be pummeled with road debris at speed.

Other then that it will work.

What would be wrong wilth using 110v LED floodlight , on motorcycle , it works at 96v dc ?

How many lumens? A flood beam is wide and doesn't project long distances. If you are riding on the street, then it will blind cars, etc. since you can't point/direct the light down enough, and then it's just illuminating close range stuff, which isn't useful at ebike speeds. For offroad, you want a combo spot/flood beam that project far enough forward by still illuminate stuff to either side in case you need to maneuver/turn, etc.

Maybe budeye one for high one for low beam?
 
I see you have removed to screw fitting at the bottom.

Have you bypassed the rectifier, or have you applied the voltage to the input of the rectifier?

That’s smart. I wasn’t aware you could do that. It’s going to look a bit strange on your bike though.

A lot of LED drivers just use a bridge rectifier and zener diode to set the voltage, so should pass through DC voltage/current without modification if the voltages are similar.
 
Nah, looks like too much faffing around to mount the thing. Maybe Google “led corn light“ and find a smaller one with a bayonet fitting that you don’t need to take to bits to fit inside your headlight.

Duct tape! Duct taping it to a helmet could solve the high/low beam issues with just a nod of the head.
 
I have run AC LED light bulbs (and before that, CFLs) directly on 36V bike batteries, for mobile display advertising. Not all of them work that way, and their light output was noticeably diminished versus plug power, but I just used a few extra lamps to get the total illumination we needed.

Given how dirt cheap internally rectified LED lighting has become, I'd just buy some and try them out.
