Horn Assembly Problems of Cadillac CTS

I was travelling approximately 65 mph at around 7pm when a dump truck suddenly moved into my lane. I had to immediately slam on the brakes. Simultaneously, I sounded my horn and flicked my high beams multiple times at which point all of my outside lights went off. I was completely in the dark, travelling in excess of 55 mph, with no street lights and no car lights. I slowed as quickly as I could and pulled over to the side of the road. I turned the car off and then restarted. Once the car restarted, the lights came back on and functioned normally. I experienced this a second time on the night of November 18, 2014 once more around 7pm. I was attempting to pass a slower vehicle. I shifted my Cts into sport transmission mode in order to downshift to pass. At the same time, I put my signal on to indicate I was moving my car to the left to pass. I passed the vehicle, put my signal on to indicate I was moving to the right, and all of my exterior lights went out. Unlike the first time this occurred, I was not engaging any controls for my lights or horn. I was simply passing and using my turn signal. Once more, I was moving in excess of 55 mph with no lights on a rural road. Fortunately, I was familiar with this road, so I was able to find a safe place to pull over, shut the vehicle off, and restart. Just like the October 2014 occurrence, when the vehicle restarted, the lights returned to normal functioning.
