03 tahoe headlight problem

Headlight assemblys were replaced with new factory units with new bulbs and one is brighter the other is very dim
Bulbs werent touched and no broken wires...

Easy thing to try and is to just swap the bulbs side to side.

Bad new bulbs can happen.

Sounds like a grounding issue.

The grounds for the head lamp harness terminate under the radiator support to the frame.

pull them off and clean the area where they bolt up. Also make sure the connectors are not corroded.
