I am thinking about getting these lights for my 2020 and have a couple of questions:
1. How do you like them?
2. Do you need the switch? I would like to wire them to be on all the time at about 20% and then go up to 100% when I turn on my high beams. What I don't know, and Denali doesn't really say, is if you need any of their switches to make that happen or if D3's w/ datadim technology can do it without any extra Denali specific harness/switch.

I like them very much - the DRL6 that I added to the back; and the Denali D3 lights to the front.Just riding this morning in some early morning fog only reinforced the fact that the D3s not only help you see ahead but also have you be seen by vehicles ahead of you.
In regard to your second question I would go to the Denali website and check the installation instructions for the D3 lights for the appropriate instructions. Off the top of my head here's what I seems to recall - you don't need a switch if you want to just use a posi-tap to the low beam lights. When you turn them on the bike the D3s will illuminate. If you wish to have the lights turn on with the low beam, and then brighten using the high beams then you will need to use a posi-tap to both the low beam and the high beam wires, and use a switch to choose whether you want low-beam or high beam illumination. I think that allows you to choose 50% or 100% illumination by a switch. Finally if you wish to have a variable illumination say 20% to 100% I believe that you can do so with datadim technology and a switch that allows you to choose the percentage of illumination on a circular type switch (don't know if I am using the right terminology).
Again, your best best is to check the installation instructions on the Denali website. If I understand correctly what you hope to do then you will need an upgraded harness; a circular switch that allows you to define the % of illumination, and the appropriate datadim attachment to allow you to make the setup do what you want it to do.
