Shimano Dynamo hub and LED head light cheap 700C road bike

I wanted to add a dynamo hub and an LED headlight to the front wheel of my bike. I detached all spokes from the original front wheel and moved them to a new one, while having a little hassle to connect the light to the hub. A similar one here: https://amzn.to/3n8qI8B NOTE that for actual cycling performance, choose a light that fits the requirement of a hub. The light shown in the video is for only up to 0.9W.
