To get better and brighter lighting on the 2016, 2017, or 2018 Chevy Silverado 1500, you'll need to upgrade to aftermarket LED assemblies. You can find some on eBay or other aftermarket shops for about $200-$400 apiece.
Since this truck only comes equipped with factory HIDs from 2016 through 2018, your only options are to get replacement D3S (D5S) bulbs or swap out the assemblies for better ones.
Although some HID to LED conversion kits exist, we advise against them as they can be quite expensive and the results disappointing since LEDs tend to perform poorly in projector headlights.
