Headlight Switch problems of the 2006 Toyota Camry

My mother has a 2006 Toyota Camry. At night, I noticed her driving without her headlights on. I stopped her, and we got her headlights on. Later, I was driving her Camry at night, and I noticed the instrument lights were on, but the headlights were off. The only setting to get the headlights on turned off the instruments lights. This is a dangerous situation. I went to the huntsville Toyota dealership. A mechanic jiggled the switch, and everything went back to normal. It is obvious the Toyota mechanics know about this problem and know how to fix it. Now, I have to worry everytime I or my mom drive the Camry that we don't jiggle the switch to cause the above problem. It is a major inconvenience and a safety hazard because one day we may forget and accidentally jiggle the switch and drive at night with the instruments light on and the headlights off. The headlight switch must be recalled!!!!.
