Hoping someone can help me out:
Why on one side of the Terrain is the DRL only lighting up on the top and not all around that horseshoe shape like the other side? See photo for the issue. Any help is appreciated.

The DRL LED Control Unit Module on that light may have gone bad. Many places will say the whole headlight has to be replaced, however the Module itself can be swapped out for much less. The hardest part of the whole job is getting the headlight out to swap out the module.

Definitely a difference when standing in front, head on. The one side is far less bright.
