Narrative:

During taxi in, left wing tip came in contact with a deice truck. The aircraft was in proper position and following the lead. Also 2 wing tip walkers were present at each wing. There was no signal given that the wing would not clear the truck. I believe the very dark ramp area was the main cause.
