Tail Light Switch problems of the 2013 Mazda MAZDA3

My headlights dim and flicker, most noticeably when applying the brakes. It was barely noticable at first. My son-in-law, who is an auto and diesel mechanic, brought it to my attention in December 2017 when he was driving it. It is getting worse and becoming more and more of a problem, making it hard to see, especially when approaching a stop at an intersection. I am not sure if the tail lights are also effected, but complaint id 11164134 reported that their's were. My experience with electrical problems causes me to worry that there is a possibility that the headlights will fail entirely, leaving me unable to see while driving at night. This is not a single incident; it always occurs everytime I drive at night, so I am putting today's date in the "when did this happen" field because I can't indicate that it is an ongoing problem. The four complaints about this same problem all indicate no injuries or fatalities; I hope there don't have to be injuries or fatalities for this to be considered serious enough to warrant a recall. Also, the speed doesn't matter, I had to put in a number so I indicated 45 mph, but it happens on the freeway at 80 mph as well as on city streets. There are currently 49,259 miles on the car. When I bought it it had 33,370 miles on it. Like I said, it is getting worse. It is more distracting due to more pronounced flickering and dimming of the illumination of the road.
