Just wanted to share a 3d printable adapter I created to fit 9005 bulbs for the reverse lights. Didn't seem like there were any really good options for LED 3157 bulbs out there so I decided to adapt 9005 bulbs. They are somewhat a work in progress because 9005 bulb bases don't seem to be that standardized so they fit the bulbs I used but you may have to modify so other bulb's mounting tabs line up. The gasket from the factory bulb holder should be fitted on the new adapter to create a dust and water resistant seal. I would recommend printing in PETG or ABS for better heat resistance especially if you live in a hot climate. I built them for my 2003 Avalanche, not sure if they fit second generation Avalanches or any other GM vehicles.

Here is the Thingiverse link with the files:

I used cheap 9005 led bulbs from Aliexpress. NO CANBUS + 6000k + 9005/HB3

For wiring an adapter harness can be made from a 9005 socket and 3157 male adapter. Or I just cut the ends of the factory harness and spliced the 9005 connector on. Links below:
