First officer reported a Leading Edge Flaps in Transit light on approach. The flight crew requested vectors for troubleshooting and to perform the QRH procedures. The flight crew then resumed the approach to landing at destination airport.

Narrative

Descending to 8;000 feet we were assigned speed 190 knots. After selecting flaps 1; Autopilot A kicked off. I started to hand fly; and we noticed the lower amber band was above the flaps 1 maneuver bug. We selected flaps 5; the amber band did not move and then the First Officer (Pilot Monitoring) noticed the amber LE FLAPS TRANSIT was illuminated and flaps indicated < 1. We requested delay vectors from ATC and I transferred the plane and radios to the First Officer. We settled on the Trailing Edge Flap Disagree checklist in the Quick Reference Handbook. The alternate flap extension moved the flaps only to just above 1. We pulled up flap 1 data on the ACARS; and also referred to flaps up data provided by Dispatch to ensure we were able to safely land on Runway XXL. The approach and landing we uneventful; taxing clear at Taxiway N with normal braking. After parking we noticed the Proximity Electronics Unit light. Just request priority handling when dealing with flap issues; we initially did not and then got deep in the checklist and setting up for the approach and didn't think about it again.
