Headlight Switch problems of the 1999 Dodge Ram 1500

My problem or complaint is this. One night I was driving my 1999 Dodge Ram 1500 quad cab to work. I was on the highway when my lights failed. The driving lights, low and high beams just went out. I have a 23 mile commute one way. Working at night I was placed in a bad situation. The only thing I had was my parking lights and flashers. I pulled over and waited for the state police, since they did not come. I drove to work with my flashers on. The good newsis my luck did not run out I made it to work unharmed. In the morning I drove my truck home and looked up the electrical system and found there is no fuses in this circuit. I spoke with my cousin who also has a ram and found out that he has gone through 3 switches. Would this be considered a safety hazard? if I had been driving on a winding road at night and the same thing had happened, I would be replacing my truck and not just the $75. 00 dealer only switch. I know their are a lot of these trucks out there and to find out that there has been 4 switches replaced in just 2 trucks. Isn't this a little high. Also, the dealer has plenty of this on hand. Which to me means, this item is a highly consumed item.
