Fog Light Switch problems of the 2015 GMC Sierra

I purchased this vehicle new August 2015. The headlight projection and illumination on this vehicle is extremely poor especially during wet roads or raining conditions. I have to use the fog lights at all times and still do not have adequate lighting. I feel this situation can and will result in serious injury or death due to lack of proper lighting. I was appalled to find out general motors only use a single halogen bulb instead of a dual filament lamp or a combination low and high beam lamps. I personally nearly hit a pedestrian during a rainy situation, and also feel unsafe operating this vehicle at dark.
