The CANBUS boxes are also an antiflicker device in some cases. This helps prevent the bulbs no coming on at times, yes, but it does this by protecting the relays from the stress of the flickering. It often is not even noticeable but it will cause the relays to fail. The best way to do it is with the relays, capacitors, and then the CANBUS / antiflicker modules, then the HID bulbs.
As far as LED vs. HID, Ive tried both, and although LED’s are better, I’m absolutely an HID fan. They are far superior to both the halogen and LED options. According to my vendor of choice, xenondepot, the halogens are approximately 1000 lumens, vs. 1750 for the LED, vs. 3200 for a 3200K HID, which is what I’m running in my ‘15.
The wiring is a bit more cumbersome, but 100% worth it in my opinion. The HIDs are soooo much better.
I did the same thing with my ‘16 Silverado 2500 that came with halogens.
I too second that it’s absurd that these manufacturers sell $60k plus vehicles with halogens. Ridiculous!
