This video is the properly working light.
I am really impressed with how well my iPhone did this cold morning. It shows the light produced well. Even the color seems to be about right,
There is a bit of light spill from the car headlamps but this reduces as I pan to the right.
The wind is blowing strongly from behind me so the audio is pretty good, unlike the other video this morning, when the iPhone is right into the wind.
Shows here is a vertical configuration DIY lamp design.
