UPDATE:
I have spoken with DENALI and they confirm that using the extension leads as mentioned below is perfectly fine. You can also use there other cable extensions, the ones with double plugs on the end.

ORIGINAL DESCRIPTION
I am no expert folks , If In doubt , seek professional advice👍This is how I fitted the D3’s to my 2022 GS. Enjoy 😊

Denali D3's have been out for a little while now.

I prefer the "ROUND" light as opposed to the "SQUARE" D4. So no adverse comments please!

The hybrid lens is street legal in the USA and Europe and the spot lens is "E" marked, so I believe it is street legal in Europe and the UK?

The spot lens, when installed, has a great reach, MORE than the D7, have a look at the in-house Denali video on this    • Best LED Motorcycle Light? - DENALI D...  

I already have the HexEzcan installed, so to fit the lights , take all panels off, route cables etc will take about 2 hours(not 1 hour and 15 minutes as I say in the video!!)

Once installed , very easy to programme the lights via a laptop using the Denali app.

Cost, for the pair of D3's, 4 extension cables and the light mounting for the crash bars was £469.

Take your time , fairly simple to install.

Just got to take them out for a night ride to adjust the lights .
