Turn Signal Switch problems of the 2012 Chevrolet Corvette

I own a 2012 Corvette grandsport purchased new. Car has 12,635 miles in it. I was driving into town last night and head lights just shut off leaving me in complete darkness. I was coming into tuscaloosa and managed was fortunate to have enough area lighting to safely come to a stop and pull into a parking lot. I tried what I knew to try but lights would not come back on. I was able to hold the turn signal switch in the flash position to get high beams to work. I turned around and headed back home continuing to hold turn signal switch in flash position. Unfortunately, I was blinding the oncoming traffic. I can't imagine what might've happened if I had been on a country road with no lightning. I've been reading about recall issues on earlier models of the c6 I've also read this could be a faulty relay problem. My car has low miles and less than 25% of those miles were night driving. Car is garage kept and has never been driven in the rain so I know how well it has been taken care of. Please advise if others have had same problem.
