Reverse Light 9005 Bulb Adapter – 2003 Chevrolet Avalanche

3D-printed replacement reverse light 9005 bulb adapter made for the 2003 Chevrolet Avalanche: a simple way to replace a cracked, lost or hard-to-find original part.

About this part

Update 4/4/2023 - Uploaded a version 2 that should be more compatible with different bulbs. I swapped the bulb to one without a fan because the fan noise bugged me. Also the locking tab is more flexible.

Created an adapter to fit 9005 bulbs for the reverse lights on my 2003 Chevy Avalanche. The gasket from the factory bulb holder should be fitted on the new adapter. The adapter should create a dust and water resistive seal. I built the 9005 slots based on the led bulbs I ordered. The mounting tabs on 9005 bulbs do not seem to be modified for other 9005 bulbs.

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. Links below:

I would recommend printing in PETG or ABS for better heat resistance especially if you live in a hot climate.
