Fog Light Switch problems of the 2017 Toyota RAV4

While operating the vehicle all front headlamps failed simultaneously leaving me in the dark. Dealer next day found both front headlamp bulbs had both low and high beam filaments burned out! this may have been a catastrophic accident but for my fog lights. How can anyone feel safe in a vehicle in which all lights might fail while driving unlit curvy roadways?.

All exterior lights: headlights, fog lights, brake lights turn signals etc. Have all been replaced at least twice in less than 4 years and 75k miles of use. I was told that perhaps the probmem is that the area around tbe bulbs is too small causing them to over heat, which could be dangerous.
