The Nissan Path

So whenever i get up past 60 mph for some ungoddly reason my transfer light comes on in the dash but its not steady it flickers recently used the transfer in some heavy snow but since that day i never had this problem i think its the transfer switch that activates that light but im not 100% sure, and other advice? Thanx 87pathfinder /5spd

It primarily does it when my foot is just gently on the gas.
