The 07-14 Denali headlamps are solely for incandescent lamps. They were subpar when new. The only way to get more light on the ground, unfortunately, is to change the assemblies.
I went to a set up on our 08 similar to this but never upgraded to HID. Didn’t use LED because the older LED technology wreaked havoc with the BCM.

The above lamps with the LED bulbs and integrated cooling fans act as resistors. They work flawlessly with no trouble codes or BCM problems.
Ursprung Upgraded H1 Light Bulbs, 100W 600% Brighter, 1:1 Size H1 Bulbs, Pack of 2
The low beams run through projectors so 100% of light gets put on the road. Both hi & low beams run H1. The high beams are not projector so they may blind the ship out of oncoming traffic but they shouldn’t be on for oncoming traffic anyway.
And you like the lighting upgrade from those eBay housings vs. the OEM housings?No before or after pics unfortunately. I can tell you that those particular LED bulbs are also identical in size to regular incandescent bulbs so they’re plug n play without needing to rotate the bulb for adjustment.
