Narrative:
At approximately XA30 while flying on a heading of 040 degrees at 4000 ft and 250 KTS; the leading edge flap transit light came on. We had not configured the aircraft; so flap and slat were up and retracted. We followed the flight control matrix and determined that the leading edge flap transit light was the correct checklist to utilize. Due to environmental conditions and aircraft weight I elected to divert and used the longer runways at ZZZ1 airport. We landed without incident. Maintenance inspected the aircraft and found a leading edge electrical contact broken.

Narrative: AT APPROX XA30 WHILE FLYING ON A HDG OF 040 DEGS AT 4000 FT AND 250 KTS; THE LEADING EDGE FLAP TRANSIT LIGHT CAME ON. WE HAD NOT CONFIGURED THE ACFT; SO FLAP AND SLAT WERE UP AND RETRACTED. WE FOLLOWED THE FLT CTL MATRIX AND DETERMINED THAT THE LEADING EDGE FLAP TRANSIT LIGHT WAS THE CORRECT CHKLIST TO UTILIZE. DUE TO ENVIRONMENTAL CONDITIONS AND ACFT WT I ELECTED TO DIVERT AND USED THE LONGER RWYS AT ZZZ1 ARPT. WE LANDED WITHOUT INCIDENT. MAINT INSPECTED THE ACFT AND FOUND A LEADING EDGE ELECTRICAL CONTACT BROKEN.
