## Discrepancy

During Flight #3101, the LH Main Landing gear didn't show down and locked.  Completed QRH and cycled gear.  All 3 showed down and locked, then the LH Green light flickered off/on several times, continued to flicker while taxing to the gate.  Maintenance replaced LH Main Gear Downlock Switch, PN Air130902, all checks good.  All work done IAW Saab MM Chap 32-61-05.
