Narrative:

During final approach with ceiling of 1600 ft and visibility 10 SM in light rain; we lowered the gear then flaps to 20 degrees and the 'leading edge' light illuminated along with a leading edge flap asymmetry EICAS message. We initiated a missed approach; completed the QRH procedures; and returned to land. I had the fire equipment standing by as a precaution. Landing and rollout were uneventful.
